Answer:
the accleration is decreasing
Explanation:
I hpe so
Answer:
0.264moles
Explanation:
number of moles= given mass/molar mass.
Molar mass of Cu2SO4= 63.5+32+4(16)=159.5
moles(n)=42.2/159.5= 0.264moles
mass h
<h3>
</h3>
Explanation:
molar mass is equal to number of mass over moles we take 14.19 over17 molar mass of ammammonium equals 0.8347 incase of moles. 1H=1Nh3 ,so. n.H=0.8347 Mr=2 ,M.H=? Mr=m/n. 0.8347x2=1.669grams
Do you have a picture of the diagram? If it looks like the one I attached, the one pointing up is normal force, the one pointing down is gravity, the one pointing to the right is applied force and the one pointing left is friction. Hope that helps
Answer:
False
Explanation:
Science is not based on primarily on peoples opinions and views of the subject matter whereas science is based on empirical observations and research for its validity.
<u>Science aims to find answers to human questions related to the natural world through their research observation and experiments. Scientists and researchers provide valid proof of human questions so that people can trust them.</u>
Science can change people's opinions regarding the natural world with valid proof and observational theories but science is not based on people's opinion.
Hence, the given statement is "false".
