The quantity of milk that will the lamb give in 24 hours is 2.32 Liter.
What is a Lamb?Lamb may be defined as the youngest form of sheep. In other words, it may be characterized as the little offspring produced by a sheep.
According to the question,
The amount of milk given by lamb in three hours = 290 milliliters.
∴ The amount of milk given by lamb in one hour = 96.66 milliliters.
Now, the amount of milk given by a lamb in 24 hours = 24 × 96.66 = 2320 milliliters.
Now, as per the requirement of the question, convert milliliter into liter.
One liter = 1000 milliliters.
∴2320 milliliters = 2320/1000 = 2.32 liters.
Therefore, the quantity of milk that will the lamb give in 24 hours is 2.32 Liter.

Calculate the number of grams of sulfuric acid in 1 gallon of battery acid if the solution has a density of 1.30 g/mL and is 38.8 % sulfuric acid by mass.
Answer:
The number of grams of sulfuric acid in 1 gallon of battery acid is 1909.4 g.
Explanation:
We have:
V = 1 gallon = 3785.4 mL
% m/m = 38.8 %
The number of grams of sulfuric acid can be calculated as follows:
[tex] m = 1.30 \frac{g}{mL}*3785.4 mL*\frac{38.8}{100} = 1909.4 g [/tex]
Hence, the number of grams of sulfuric acid in 1 gallon of battery acid is 1909.4 g.

What is the coefficient of hydrogen, H 2, when the following equation is balanced? Al + H 2SO 4 → Al 2(SO 4) 3 + ? H 2
Answer:
3
Explanation:
Balancing the equation:
Original equation: Al + H2SO4 → AL2(SO4)3 + H2
We see that in aluminum in AL2(SO4)3 there is a subscript 2.
We put a 2 in the front of the reactant Al.
We also see a subscript 3 behind (SO4).
We add a 3 in front of H2SO4.
Now we have to balance the H2 on both sides. We add a 3 in front of the H2 on the right as there is 3 H2 molecules on the left.
2Al + 3H2SO4 → AL2(SO4)3 + 3H2

What is the speed of a man that travels 2 meters in 6.5 seconds?
Answer:
0.305556 m / s
Explanation:
Speed = distance / time
2 metres = 0.002 km
6.5 sec = 0.00180556 hrs
Therefore,
Speed = 0.002 / 0.00180556
= 1.1 km / hr
= 0.305556 m / s
≈ 0.31 m/s
Explanation:v = d/t
= 2m/6.5s
= 0.3079 m/s
≈ 0.31 m/s
A 1.0 mole pure sample of molten tin is dissolved in a 5.0 mole pure sample of molten copper. The solution is set aside to cool and solidify. The atomic radius of tin is 140 pm and the atomic radius of copper is 128 pm. a. Identify the type of alloy that is formed. Justify your answer. b. Identify the solvent in this solution. Justify your answer.
Answer:
a. Bronze
b. Copper
Explanation:
a. The alloy formed from the mixture of molten tin and molten copper, with copper having the over triple of the quantity of tin, is bronze. Although, these two metals are often not the only metals present in bronze.
b. The solvent in this mixture is molten copper. This is because, it has the larger percentage of the constituents and hence can easily allow other constituents to be dissolved in it.
The characteristics of the mixtures allow to find the answers to this question about bronze are:
We have a homogeneous solution The solute is tin and the solvent is copper
In chemistry when materials do not react with each other, a new compound is not formed, therefore there is a mixture of unreacted elements.
The mixture is the union of two or more components united, but that do not react chemically, we can have two types of mixture:
Homogeneous. In this case the materials cannot be distinguished from each other, this special case is called a solution. Heterogeneous. There is a heterogeneous composition that can be distinguished. The parts of can be separated by physical methods, for example: deposition in time, filtration, etc.
In mixtures, the material that is in less quantity is called solute and the material that is in greater quantity is called solvent.
In this case we have a combination of Tin and Copper, by heating when they are taken to the liquid state the mixture is formed, the result is a material where no phase or separation can be distinguished, therefore we are in the presence of a homogeneous solution, that cooling would be a solid solution.
Therefore, copper and tin maintain their chemical properties, but the physical properties are altered, this solution is widely used industrially and is called Bronze.
We have 1 mole of tin and 5 moles of Copper, so the solute is the material in the least amount of Tin and the solvent is the material in the greatest amount of Copper.
In conclusion, using the characteristics of the mixtures we can find the answer to this question about bronze:
We have a homogeneous solution in solid state The solute is tin and the solvent is copper

A pure sample of gold has a volume of 25.0 cm and a mass of 483 g. What is the density of gold?
0 cm
0.0514 g/cm3
0.00197 g/cm
19.4 g/cm
508 g/cm3
Answer:
the correct answer is D
Explanation:
The density of gold is 19.4g/cm
The density of gold is found to be 19.32 g/[tex]cm^3[/tex] when it has a volume of 25.0 cm and a mass of 483 g.
What is density?Density may be defined as a type of physical quantity that describes the mass per unit volume of any substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. It is commonly expressed in units of grams per cubic centimeter.
It is a word we use to describe how much space an object or substance takes up (its volume) in relation to the amount of matter in that object or substance (it's mass).
Another way to put it is that density is the amount of mass per unit of volume. If an object is heavy and compact, it has a high density.
According to the context of this question,
The mass of gold = 483 g
The volume of a pure sample of gold = 25.0 cm.
The formula for calculating density is as follows:
Density = Mass/Volume.= 483g/25.0 cm = 19.32 g/[tex]cm^3[/tex].
Therefore, the density of gold is found to be 19.32 g/[tex]cm^3[/tex] when it has a volume of 25.0 cm and a mass of 483 g.

Hint: Convert lbs to kg to g then solve for volume.
a: 19.9 mL
b: 50.1 mL
C: 11.0 mL
D: 33.4 ml
Answer:
The answer is option BExplanation:
The denisty of a substance can be found by using the formula
[tex]Density(\rho) = \frac{mass}{volume} [/tex]Making volume the subject we have
[tex]volume = \frac{mass}{Density} [/tex]From the question
Density = 13.6 g/cm³
mass = 1.50 lbs
We must first convert the lbs to grams in order to solve
That's
if 2.2 lbs = 1 kg
Then 1.50 lbs = [tex] \frac{1.5}{2.2} [/tex]
= 0.681 kg
If 1 kg = 1000 g
Then 0.68 kg = 0.681 × 1000 = 681g
So the mass = 681 g
Substitute the values into the above formula and solve for the volume
That's
[tex]volume = \frac{681}{13.6} [/tex]= 50.0735

9.1 x 10−13kg is equal to how many ng.
Answer:
.91 ng
Explanation:
So for the first one the conversion factor which is the first blank in your first question is (1/100) and the second blank which would be (74)(1/100) is 0.0174
The second one would have two conversion factors where the first blank would convert to grams, so the conversion factor for the first blank is (1000/1), then converting from grams to nano grams, whose conversion factor is (1,000,000,000/1).
So in general the second one is 9.1 x 10^-13 (1000/1) x (1,000,000,000/1) = .91 ng
Hope my explanation is easy to understand.- Ryan Brown indy
9.1 x 10-¹³ kg is equal to 0.91 nanograms (ng).
CONVERT MASS IN kg TO g
Kilograms and grams are both interconvertible units of mass. The conversion ratio of kg to grams is as follows:1000 grams = 1 kilogram
Hence, 9.1 x 10-¹³ kg is equal to (9.1 x 10-¹³ × 10³)= 9.1 x 10^(-13+3)
= 9.1 × 10-¹⁰ grams.
CONVERT MASS IN g TO ng
The conversion ratio of grams to nanograms (ng) is as follows:1gram = 1000000000 (10⁹) nanograms
Hence, 9.1 × 10-¹⁰ grams = 9.1 × 10-¹⁰ × 10⁹= 9.1 × 10^(-10 + 9)
= 9.1 × 10-¹
= 0.91 nanograms (ng).
Therefore, 9.1 x 10-¹³ kg is equal to 0.91 nanograms (ng).

The density of the osmium is 22.57 g/cm^3 the volume would be occupied by 1.50 kg of osmium will be 33.85 ml.
What is density?The density of a substance is the division of mass of the given substance and the volume of the given substance and its unit will be centimeter cube and it cannot be effect by the temperature.
The density can be calculated by the formula
Density = mass of substance / volume of substance in liter
Density = 22.57 g/cm³
mass = 1.50 kg
Substituting the value in the equation,
22.57 g/cm³ = 1.50 kg / volume
Volume = 22.75 g/cm³ × 1.50 kg
volume = 33.85 ml

Answer:
The basketball has a constant negative acceleration due to gravity when it is thrown
Explanation:
Before the basket ball is thrown, and when the basket ball is in free fall flight it is always under and experiences an attractive force between the Earth and all objects on Earth known as gravitational force such that the direction of the acceleration of the gravitational force is always towards the Earth and therefore, downwards, resulting in an increasing decreased upward speed of the thrown ball in the projectile motion, equivalent to the ball having a negative acceleration, same as all objects in free fall.
