How many molecules of CrCl₃ are produced when 2.89 moles of CuCl₂ react? * 2Cr+3CuCI2-2CrCI3+3Cu

Chemistry
1 answer:
juin [17]2 years ago
3 0

Explanation:

The reaction is CaCO

3

+2HCl→CaCl

2

+H

2

O+CO

2

.

Thus, 2 moles of HCl reacts with one mole of calcium carbonate to produce one mole each of calcium chloride, water and carbon dioxide respectively.

Hence, 3 moles of HCl will react with excess of calcium carbonate to produce 3×

1

=1.5 mol of carbon dioxide

These goats are eating grass on a sunny day. What is happening to the carbon in the air around the living things on the mountain
polet [3.4K]

Answer:

both

Explanation:

Carbon in the air around the living thing is moving in and out of its lungs. The movement is occurring at the same time. This is one of the most important gaseous exchange important to life.

  • The goats takes in oxygen gas from the surrounding and releases carbon dioxide in the process.
  • But, air is actually drawn in by the goat which is a mixture of several gases.
  • Air contains carbon dioxide which is a rich source of carbon
  • With the carbon dioxide from respiratory processes, the goat ejects and breathes out this waste carbon matter.
  • Therefore, the gaseous exchange in a goat involves the movement of carbon in and out of the air.

Chemistry an atom of strontium has at least four different isotopes. what is different between an isotope of 86sr and an isotope
lions [1.4K]
Isotopes are atoms of the same element that differ in the number of neutrons.

Remember that all the atoms of an element have the same number of protons. So the only difference between isotopes of an element is the number of neutrons.

86 Sr means that the mass number of this isotope is 86. Also, remember that the mass number is the number of protons plus the number of neutrons.

87 Sr means that the mass number of this isotope is 87.

So, 86 Sr and 87 Sr differ 1 neutron.

Answer: 1 neutron
