Answer: the answer is hydrogen
Do you mean cm^3?
The density of gold is 19.32 grams / cm^3
d = mass / volume
19.32 = mass/ 4.58 cm^3
19.32 * 4.58 = 88.5 grams
Answer:
CO₂ + 4 H₂S + O₂ ---> CH₂O + 4 S + 3 H₂O
Explanation:
The unbalanced equation looks like this:
CO₂ + H₂S + O₂ ---> CH₂O + S + H₂O
Below is the amount of each element on each side of the reaction.
Reactants:
> 1 carbon, 2 hydrogens, 1 sulfur, 4 oxygens
Products:
> 1 carbon, 4 hydrogens, 1 sulfur, 2 oxygens
As you can see, there is a differing amount of hydrogens and oxygens on both sides. The balanced equation looks like this:
1 CO₂ + 4 H₂S + 1 O₂ ---> 1 CH₂O + 4 S + 3 H₂O
Below is the amount of each element on each side of the reaction.
Reactants:
> 1 carbon, 8 hydrogens, 4 sulfurs, 4 oxygens
Products:
> 1 carbon, 8 hydrogens, 4 sulfurs, 4 oxygens
Answer:
His speed was 2 m/s, and his velocity was 0
Explanation:
In physics, speed of an object is defined as the change in position with the change in its time. While velocity may be defined as the change in the position of the body with respect to the time taken.
Speed in a scalar quantity which means it has only magnitude while velocity has both magnitude and direction.
To determine change in velocity both direction as well as magnitude has to be changed.
In the context, Kai was 200 m of the library in the north direction. Now for the round trip to the library and back to his position, Kai took 200 seconds time to cover the distance.
So for the round trip, the speed of Kai would be 2 m/s abut the velocity of Kai is 0 as the displacement of Kai is 0.
Explanation:im not really sure about this one but i think it is either c or b
ANSWER:C im pretty sure.sorry if wrong
