Answer:
B
Explanation:
Generally, when you dilute something, your goal is to thin your concentration. Even if you added a solute, if your goal is dilution, it will make the concentration decrease.
The answer is going to be (a) - oxygen. this is because, for this reaction, charcoal undergoes a combustion reaction, using the oxygen from the surrounding atmosphere to burn to heat, light and CO2.
hope this helps!!
Answer:
the partial of colloidal are smaller and they are not heavy whereas the partial of suspension are larger but they are heavy and less movement thus they settle down due to gravity
Answer:
D. The coefficients give the ratio of mole reactant to moles product.
Explanation:
In stoichiometric calculations, the amount of product formed from reactants can be determined.
- Using this approach, the number of moles of reactants and products on both sides of the expression must be balanced.
- As a rule of thumb, the coefficients give the ratio of moles of reactants to moles of products.
- This is very useful in a number of calculations using the stoichiometric approach.
Explanation:
Our environment is very important to us because it is where we live and share resources with other species. ... Environmental science enlightens us on how to conserve our environment in the face of increasing human population growth and anthropogenic activities that degrade natural resources and ecosystems.
