LAST ATTEMPT! Covalent compound naming !

Answer:

10m\s

Explanation:

given

initial velocity(u)=0

final velocity (v)=100

acceleration(a)=?

we know,

acceleration = v-u/t

= 100-0\10

= 10 m\s

Answer:

an electric field is a field around a charged particle or object within which a force ( electric force) would be exerted on other charged particles or objects.

Explanation:

particles with unlike charges attract one another while particles with like charges repel each other.

Explanation:

Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. ... Electric charge is carried by subatomic particles. In ordinary matter, negativecharge is carried by electrons, and positive charge is carried by the protons in the nuclei of atoms.

Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. There are two types of electric charge: positive and negative (commonly carried by protons and electrons respectively). Like charges repel and unlike attract. An object with an absence of net charge is referred to as neutral. Early knowledge of how charged substances interact is now called classical electrodynamics, and is still accurate for problems that do not require consideration of quantum effects.

Answer:

We have to convert the following into moles.

(a) 32 g of oxygen gas = 1 mole

1 gram of oxygen gas = 1/32 mole

Given that 12 g of oxygen gas

No: of moles = given mass / molar mass

= 12 / 32  = 0.375 mole

(b) 18 g of water = 1 mole

1 gram of water = 1/18 mole

Given that 20 g of water

No: of moles = given mass / molar mass

= 20 / 18  = 1.111 mole

(c) 44 g of carbon dioxide = 1 mole

1 gram of CO2 = 1/44 mole

Given that 22 g of carbon dioxide

No: of moles = given mass / molar mass

= 22 / 44 = 0.5 mole

Explanation:

Since the increase in boiling point with increasing pressure is fairly constant, then, the boiling point at 1.5 atmospheres could be predicted fairly well.

We say that a substance has reached its boiling point when its pressure equals the atmospheric pressure. Recall that we can be able to make predictions from the results of an experiment.

In this case, we are told that there is a nearly constant increase in boiling point for each increase in pressure. Therefore, it is reasonable to conclude that, a boiling point at 1.5 atmospheres could be predicted fairly well.

Since the heat of combustion of butane is higher than that of propane,  butane will produce more heat per gram when burned compared to propane.

The heat of combustion of a compound refers to the heat evolved when one mole of the compound is burnt under standard conditions. This heat of combustion increases from methane upwards.

Since the heat of combustion of alkanes increases according to increasing molar mass, butane will produce more heat per gram when burned compared to propane.

From the question,

We are to identify the binary salt among the given salts.

First, we will define the term binary salt

A binary salt is a chemical compound that is formed from the mixture of a metal and a non-metal.

Among the given options, CaCl₂ is the salt formed from the mixture of a metal and a non-metal.

The metal is Calcium (Ca)

and the non-metal is Chlorine (Cl)

Hence, the binary salt among the given salts is CaCl₂. The correct option is d,CaCl₂

Answer:

Scientific laws or laws of science are statements, based on repeated experiments or observations, that describe or predict a range of natural phenomena. Scientific law differs from scientific theory. The main difference between a law and a theory is that a theory tries to explain the reasoning behind something that occurs in nature, whereas scientific laws are just descriptive accounts of how something occurs in nature.
