Answer: i think it is Habitat but i am not 100%
Explanation:
Answer: Option (C) is the correct answer.
Explanation:
A physical substance that occupies space and has mass is called matter. Every matter possesses some chemical and physical properties.
Chemical property is the property which occurs when there is change in chemical composition of matter. Whereas physical property is the property which occurs when there is change in the appearance of matter.
The chemical properties of matter does not depend on temperature, therefore, option (a) is not correct.
Every matter posses some mass therefore, option (b) is also not correct.
It is possible for matter to have similar chemical properties and different physical properties. For example, a very small piece of sodium and a very large piece of sodium will react chemically in the same manner whereas their physical property, in this case is the size, is different. Therefore, option (c) is correct.
Every matter has some chemical and physical properties. Thus, it is not possible that matter can have only physical property and no chemical property. Hence, option (d) is also not correct.
Thus, we can conclude that the statement it is possible for matter to have similar chemical properties and different physical properties is true about matter.
Answer:
1.18 moles of CS₂ are produced by the reaction.
Explanation:
We present the reaction:
5C + 2SO₂ → CS₂ + 4CO
5 moles of carbon react to 2 moles of sulfur dioxide in order to produce 1 mol of carbon disulfide and 4 moles of carbon monoxide.
As we do not have data from the SO₂, we assume this as the excess reagent. We convert the mass of carbon to moles:
70.8 g / 12 g/mol = 5.9 moles
Ratio is 5:1, so 5 moles of carbon react to produce 1 mol of CS₂
Then, 5.9 moles will produce (5.9 . 1) / 5 = 1.18 moles
Answer:
A. Because you have to simplify
