Answer:
Explanation: n=m/M(molar mass)
n=24.3 grams/(16+2x1.008)grams/moles(molar mass of H2O)
n=24.3grams/18.016grams/moles
n=1.35moles
3 Common States of Matter:
1. Solid - particles are motionless and stick together very closely.
2. Liquid - particles are moving slowly without pattern.
3. Gas - Particles are moving rapidly again without pattern.
Answer:
0.19 kg
8 N
1.964 N
58.86 N
15 kg
Explanation:
w = Weight of an object = 100 N
g = Acceleration due to gravity of Earth = 
m = Mass of an object
Weight is given by
Mass of the object is 0.19 kg
g = 
m = 4 kg
Weight of the object is 8 N.
m = 200 g
Weight of the object is 1.964 N.
Weight is the force the Earth exerts on an object which is on the surface of the Earth.
m = 6kg
The force of the object is 58.86 N.
w = 150 N
a = g = 
Mass of the object is 15 kg.
Answer:
Me and my friends were going to do a science experiment. Jonny’s job was to make the HYPOTHESIS. He said the “ If we mix baking soda and vinegar together, the TEMPERATURE will go down.”
So then Molly mixed the baking soda and vinegar together and checked the TEMPERATURE. We all OBSERVED as the thermometer’s TEMPERATURE went down. “ your THEORY/ HYPOTHESIS was correct!” Exclaimed Molly.
Then the whole science GROUP let out with a cheer! And wrote the information down on their EXPERIMENTAL info chart. They took a microscope and looked at the mixture because they wanted to the the little PARTICLES in the mixture. Lily CONTROLED the microscope she zoomed in and out to see the particles.
