When volcanoes erupt, they emit a mixture of gases and particles into the air. Some of them, such as ash and sulphur dioxide, have a cooling effect, because they (or the substances they cause) reflect sunlight away from the earth. Others, such as CO2, cause warming by adding to the the greenhouse effect.
Answer:
182.3 g
Explanation:
number of mols of HCl = 5 mols
molecular weight of HCl = 36.46 g/mol
m = mass of HCl = number of mols x molecular weight
m = 5 mols * 36.46 g/mol
m = 182.3 g

El cubo Maggie es un sazonador que contiene caldo de pollo y grasas, por lo que se disuelve fácilmente al entrar en contacto con el agua caliente gracias a que la temperatura que derrite las grasas y se vuelven líquidas, mientras que con el agua fría no puede disolverse así de rápido ya que las grasas siguen en estado sólido.
Hello there!
The solute is salt, and the solvent is water. So the answer is #1.

Answer is: the mass of the carbon is 14.57 grams.
m(H) = 2.45; mass of hydrogen in sample of acetone.
n(H) = m(H) ÷ M(H).
n(H) = 2.45 g ÷ 1.01 g/mol.
n(H) = 2.425 mol; amount of hydrogen.
From molecular formula of acetone: n(C) : n(H) = 3 : 6 (1 : 2).
n(C) = 2.425 mol ÷ 2.
n(C) = 1.212 mol; amount of carbon in the sample.
m(C) = n(C) · M(C).
m(C) = 1.212 mol · 12.01 g/mol.
m(C) = 14.57 g.
