Answer:
Explanation:
There are many compounds that are produced from Nickel.
Molar mass of Ni = 58.7g
So for 0.235g Ni, there are 0.004M.
By conservation of mass, the compound produced will contain 0.04M of Ni.
Answer:
0.050 mol
Explanation:
The reaction that takes place is:
Then we convert 0.050 moles of phosphoric acid into moles of ammonium phosphate, using the stoichiometric coefficients of the reaction:
- 0.050 mol H₃PO₄ *
= 0.050 mol (NH₄)₃PO₄
Thus, the complete reaction of 0.050 moles of phosphoric acid would produce 0.050 moles of ammonium phosphate.
Answer:
Distillation
Explanation:
By using the method of distillation we'll identify if there is other properties of liquid by looking the temperatures,the ordor or the boiling point.
5N force was applied to an object if 35 j of work was done and the object moved 7 m
A force is an effect that can alter an object motion according to physics and an object with mass can change its velocity or accelerate as a result force and also force is as push or pull and work done by the force on an object means assuming that direction of the force is parallel to the displacement of the object
Then the formula is
W = f × d
Where f is the magnitude of force and d is the displacement of the object
Then W = 35 J is the work done and
d = 7m is the displacement of the object
So rearrange the equation then
F = 35/7 = 5N
5N force was applied to an object if 35 j of work was done and the object moved 7 m

Answer:
This is a desert because there is little precipitation for plant and animal life to thrive.
Explanation:
Tundra is harsh environment because of its cold temperature, so it's definitely not too hot. Swamp temperature should be not too cold or hot. The rainforest should have abundant plant and animal life.
Desert has very low precipitation and low moisture so that not much water can be found around. Water is vital for any plant or animal. Water also helps regulate temperature and make the fluctuation in the environment extreme. The temperature around the desert can be really high at daylight and low at night.
