How does heat differ from temperature

Chemistry

<span>Heat is the total energy of molecular motion in a substance while temperature is a measure of the average energy of molecular motion in a substance. Heat energy depends on the speed of the particles, the number of particles (the size or mass), and the type of particles in an object.</span>

How much water should be added to 70ml of 60 percent acid solution to dilute it to a 50 percent acid solution?
mestny [16]

Answer:

14 ml of water

Explanation:

To find the volume you need to dilute the concentration of a solution, you should use the formula C1 x V1 = C2 x V2 in which:

C1 = initial concentration ( in this case 60 %)

V1 = initial volume ( in this case 70 ml)

C2 = Final concentration ( you want to dilute until 50 %)

V2 = final volume ( the variable you want to search)

So you need to:

1.- Isolate the variable you want to find: V2 = (C1 x V1) / C2

2.- Substitute data: V2 = (60% x 70 ml) /50 %

3.- You do the math, in this case is 84 ml.

4.- Remember that you have a initial volume of 70 ml, so the difference (84 ml - 70 ml = 14 ml) is the volume you need to add to dilute your solution.

Which type of bonding involves the complete transfer of a valence electron from a less electronegative atom to a more electroneg
Ivan

Answer:

Ionic or electrovalent bonds

Explanation:

Ionic or electrovalent bonds are interatomic or intramolecular bonds which are formed between two kinds of atoms having a large electronegativity difference usually 2.1.

Electronegativity is the property that combines the ability of an atom to gain or lose electrons. It is expressed as the tendency with which atoms of elements attracts valence electrons in a chemical bond.

In this bond type, a metal transfers its electrons to a more electronegative atom which is a non-metal.

Balance the following equations: (c) H2(g)+I2(s)⟶HI(s)H2(g)+I2(s)⟶HI(s)
kenny6666 [7]

Answer: H_2(g)+I_2(g)\rightarrow 2HI(s)

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

Thus in the reactants, there are 2 atoms of hydrogen and 2 atoms of iodine .Thus there has to be 2 atoms of hydrogen and 2 atoms of iodine in the product as well. Thus a coefficient of 2 is placed in front of HI.

The balanced chemical reaction is:

H_2(g)+I_2(g)\rightarrow 2HI(s)
