Answer:
Chemical reactions that take place inside living things are called biochemical reactions. Explanation:The sum of all the biochemical reactions in an organism is referred to as metabolism. Metabolism includes both exothermic (heat-releasing) chemical reactions and endothermic (heat-absorbing) chemical reactions.
Answer:
Lewis structure of polyatomic formate anion.
Explanation:
To draw Lewis structure for any chemical species,
1)Count the total number of valence electrons present in it.
This can be obtained by adding valence electrons of each constituent atom.
2)Arrange those valence electrons in such a way that each atom should attain eight electrons around it to satisfy octet theory.
The structure of formate ion and its Lewis structure are shown below:
HCOO- is the formate ion.
It has total:
1+4+6+6+1 = 18 valence electrons.
Since, hydrogen has one, carbon has four and oxygen has six valence electrons and the charge of the anion is one.
Arrange this 18 electrons in such a way that each atom should get 8 electrons around it.
Resonance structures of formate ion:
Pv=nRT
where,p=199, R(constant)=8.314, V=4.67 T=30C=293K
n=pv/RT=0.38 moles
Answer:
the United States and the Soviet Union.
Explanation:
Basically we were in toe to toe with the russians for space explorations like who's gonna get to space first or moon or do such explorations
<span>We know that an ideal gas keeps the relation between pressure, volume and temperature constant.
P * V / T = constant
Then if we have the gas in two diferente state:
P1*V1/T1 = P2*V2/T2
Temperature remain constant so then:
P1*V1 = P2*V2
98.5*285 = 94.2*V2
V2 = 98.5*285/94.2 = 298 ml
So the volume of the ammonia will be 298 ml</span>
