Answer:
1. Independent variable : pendulum's height
2. Dependent variable : Pendulum speed
Explanation:
In an experiment scientist uses such things to search for any cause and its effect. experimenters design the model in such a way that change in one of the item causes a change in another.
These are called variables which are independent variable and dependent variable. Independent variables can be changed by the experimenter while dependent variables are not controllable by the experimenter.
In the context, the hypothesis is when the pendulum's height is reduced, the clock will speed up.
1. Independent variable : height of the pendulum
2. Dependent variable : Pendulum speed
Hey there :
Molar mass of NaCl = 58.44 g/mol
Number of moles :
n = mass of solute / molar mass
n = 58 / 58.44
n = 0.9924 moles of NaCl
Volume = 1.0 L
Therefore:
Molarity = number of moles / volume ( L )
Molarity = 0.9924 / 1.0
Molarity = 0.9924 M
Hope that helps!
Answer:
Natural resources are naturally formed of course(wood copper fruits) and they are not distributed evenly due to competition of getting them and the prices of the resources
Explanation:
To convert from grams to moles, you divide the number of grams by the molar mass To convert from moles to grams, you multiply by the molar mass. You must first calculate the molar mass of the substance
When methane is burned with oxygen, the products are carbon dioxide and water. If you produce 9 grams of water and 11 grams of carbon dioxide from 16 grams of oxygen, how many grams of methane were needed for the reaction? First you need to write a balanced chemical equation.
