Answer:

250 minutes

Explanation:

60 seconds = 1 minute

15000 secods = 15000 / 60

1500 secons = 250 minutes

Hey there !

Mass = 237 g

Volume 237 mL

Therefore:

Density = mass / Volume

D = 237 / 237

D = 1.0 g/mL

1.the law that the properties of the elements are periodic functions of their atomic numbers. Also called Mendeleev's law. (originally) the statement that the chemical and physical properties of the elements recur periodically when the elements are arranged in the order of their atomic weights.

Explanation:

2.Mendeleev’s Periodic Law states that the properties of elements are the periodic function of their relative atomic masses. Mendeleev arranged all 63 elements; which were discovered till his time; in the order of their increasing relative atomic masses in a tabular form. It is known as Mendeleev’s Periodic Table.

Answer:

Explanation:

25 yard [3 feet / 1 yard] [12 inches / 1 foot] = 25 * 3 * 12 = 900 inches in 25 yards.

Always put the unit you are going to on top and the unit you are coming from on the bottom.

So in this example, you want to going to feet to start with. That's on top. Yards are on the bottom of the first bracket.  In second bracket feet are on the bottom, inches are what you are going to on the top.

Heat is transferred through convection by the movement of a liquid or gas and is denoted as option D.

this is defined as the process of heat flow through a fluid which include a liquid or gas.

This process doesn't involve contact between the object unlike in conduction. A typical example is the heat flow which occurs in the atmosphere thereby making it the most appropriate choice.

Answer:

electrons are knocked off atoms, causing electricity to flow.

Explanation:

Taking into account the definition of molecular geometry, the correct option is option d.:  the bond angle of a linear molecule is 180 degrees.

In first place, molecular geometry or molecular structure is the spatial distribution of atoms around a central atom. Atoms represent regions where there is a high electron density, and are therefore considered electronic groups, regardless of the bonds they form.

That is, molecular geometry is the three-dimensional arrangement of the atoms that make up a molecule.

The molecular geometry of an element characterizes some of its physical or chemical properties, such as boiling point, viscosity, and density.

Linear molecules are molecules of the AB₂ type in which the central atom does not have lone pairs. To avoid repulsions between the binding pairs, arrange the B groups as far apart as possible. For that they must oppose each other 180 °.

In summary, linear molecular geometry describes the arrangement of different atoms with 180º bonds.

So, the correct option is option d.:  the bond angle of a linear molecule is 180 degrees.

Answer:

The particles of frosting absorbed energy from their surroundings and changed from the solid to the liquid state.

Explanation:

On a sunny day, the energy of the particles in the surrounding is higher than the energy of the frosting tray of cupcakes.

As a result of the exchange of energy between the tray of cupcakes and the surrounding, the tray of cupcakes absorbs energy from the surrounding. When this occurs, the firm frosting is now converted from solid to liquid which is runny and wet to touch, hence the answer above.

Explanation:

Molarity= No of moles of solute * 1000 / vol solution in ml

No of moles= Given mass / Molar mass

Given Mass of solute (H2O2)= 10g

Molar mass of H2O2=34gmol^-1

No of moles= 10/34= 0.294 moles

Volume of solution=50ml

Molarity =   0.294*1000 / 50

Molarity = 5.8M

NEITHER

Answer:

The answer is "Option B"

Explanation:

Law:

In the law of the conservation of matter, states the volume of matter throughout the process remains constant. In any particular case, it is closed to the movement of matter.  It is mostly on conservation of energy means, that the total mass of the products should consider the sum of the mass, which is the reactant of the event of chemical processes.
