Calcium, because when it becomes an ion, it loses two electrons and gets rid of its M shell, decreasing its ionic radius. The rest are anions, which increase in ionic radius because the effective nuclear charge decreases.
Answer:
Winds that normally blow to the east get stronger, waters off the coast of North America cool down, and upwelling increases, improving the nutrients in the water.
Explanation:
The Elinino is a group of cyclones that are created by the building up of warm water that builds up along the equator in the Pacific. In the build-up of the Elinino, the warm ocean surface warms the atmosphere which then allows the air that is rich in moisture to rise rapidly and develop into a thunderstorm. This then causes Winds that normally blow to the east get stronger, waters off the coast of North America cool down, and upwelling increases, improving the nutrients in the water.
The mass of chlorine that react with 9.00 g of Al to form AlCl3 is 35.465 grams
Explanation
write the equation for reaction
that is
2 Al + 3 Cl2 = 2 Al CL3
find the moles of Al reacted
moles = mass/molar mass
9 g/ 27 g/mol = 0.333 moles of Al
by use of mole ratio between Al to Cl2 which is 2:3 find the moles of Cl2
mole of cl2 = 0.333 x3/2 = 0.4995 moles
mass of Cl2 is therefore = moles x molar mass
= 0.4995 x71 = 35.465 moles
