zheka24 [161]3 years ago
5 0

Answer:

Chemical reactions make and break the chemical bonds between molecules, resulting in new materials as the products of the chemical reaction.

Explanation:

Breaking chemical bonds absorbs energy, while making new bonds releases energy, with the overall chemical reaction being endothermic or exothermic.

I might need a diagram for this, but I have a vague idea of what you are talking about.

If H20 is going left it means the temperature is going lower.

A virus has a mass of ×9.010−12mg and an oil tanker has a mass of ×3.0107kg . Use this information to answer the questions below
puteri [66]

Answer: Mass of one mole of viruses in grams is 54\times 10^{8}  

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to molecular mass and contains avogadro's number 6.023\times 10^{23} of particles.

Given : One virus has mass of = 9.0\times 10^{-12}mg=9.0\times 10^{-15}g     1mg=10^{-3}g

One mole of virus 6.023\times 10^{23} has mass of = \frac{9.0\times 10^{-15}}{1}\times 6.023\times 10^{23}=54\times 10^{8}g  

Thus mass of one mole of viruses in grams is 54\times 10^{8}

This problem involves a molecular compound so both empirical and molecular formulas are required. A compound compose of Carbon,
Vlad [161]

Answer:

empirical formula = CH2Br

molecular formula = C2H12Br2

Explanation:

  1. Start with the number of grams of each element, given in the problem.
  2. Convert the mass of each element to moles using the molar mass from the periodic table.
  3. Divide each mole value by the smallest number of moles calculated.
  4. Round to the nearest whole number. This is the mole ratio of the elements

In this problem:

Carbon: .3194/12.0107 = .0266

Hydrogen: .05361/1.0794 = .0532

Bromine: 2.125/79.904= .0266

Divide all three numbers by .0266 to get:

C = 1

H = 2.00

Br = 1
