This is the pattern formed in a fluid when heating causes part of the fluid to rise and then cooling causes it to sink again. Within Earth's mantle they circulate heat and drive plate tectonic processes. Within the atmosphere and oceans, they drive winds and weather patterns:Convection Cell

How many moles of copper are there in 6.93 g of copper sample<br>pls be quick

Alex_Xolod [135]

Molar mass of copper=63.5g/mol
Given mass=6.93g

$\\ \sf\longmapsto No\:of\;moles=\dfrac{Given\:mass}{Molar\:mass}$

$\\ \sf\longmapsto No\:of\:moles=\dfrac{6.93}{63.5}$

$\\ \sf\longmapsto No\:of\:moles=0.109\approx 1.11moles$

A chemist determines by measurements that 0.0800 moles of bromine liquid participate in a chemical reaction. Calculate the mass

guajiro [1.7K]

Answer:

The mass of bromine liquid that participates in a chemical reaction=12.8 g

Explanation:

We are given that

Total number of moles of bromine liquid participate in chemical reaction=0.0800 moles

We have to find the mass of bromine liquid that participates.

Atomic mass of Br=79.9 g

1 mole of bromine liquid=2 atomic mass of bromine (Br)

1 mole of bromine liquid ( $Br_2$ ) = $2\times 79.9=159.8 g$

0.0800 moles of bromine liquid= $159.8\times 0.0800$ g

0.0800 moles of bromine liquid=12.784 g

0.0800 moles of bromine liquid $\approx 12.8$ g

Hence, the mass of bromine liquid that participates in a chemical reaction=12.8 g

10. The numbers 3 and 8 in the chemical formula for propane, C3H8, are given a special name. They are called

kondaur [170]

Answer: The numbers 3 and 8 in the chemical formula for propane, $C_{3}H_{8}$ , are given a special name. They are called subscripts.

Explanation:

The chemical formula of propane is $C_{3}H_{8}$ . The numbers written at the lower end of an alphabet while writing a chemical formula are called subscripts.

For example, in $C_{3}H_{8}$ the subscripts are numbers 3 and 8.

This also means that there are 3 carbon atoms and 8 hydrogen atoms present in a molecule of propane.

Thus, we can conclude that the numbers 3 and 8 in the chemical formula for propane, $C_{3}H_{8}$ , are given a special name. They are called subscripts.
