Answer:

Answer: The formula for hypobromite $BrO^-$ .

Explanation:

Hypobromite is also called as alkaline bromine water with molecular formula of $BrO^-$ . It is used as germicide and antiparasitic

It is prepared by reacting bromine gas and alkali at 20 °C .

$Br_2+2OH^-\rightarrow Br^-+BrO^-+H_2O$

Oxidizing action of hypobromite ions.

$OBr^-+2H^++e^-\rightarrow (1)/(2)Br_2+H_2O$

Answer 2

Answer: The formula for Hypobromite is BrO

In the ground state, each atom of an element has two valence electrons. This element has a lower first ionization energy than calcium.Where is this element located on the Periodic Table?
(1) Group 1, Period 4 (3) Group 2, Period 3
(2) Group 2, Period 5 (4) Group 3, Period 4

Answers

Answer: Option (2) is the correct answer.

Explanation:

Ionization energy is defined as the energy required to remove the most loosely bound electron from a neutral gaseous atom.

And, when we move across a period then there is a decrease in the ionization energy due to decrease in the size of atoms.

Whereas when we move down a group then there is an increase in ionization energy because of increase in size of the atoms.

Since, it is given that each atom has 2 valence electrons therefore, all the atoms belong to group 2.

And, as it has lower first ionization energy than calcium it means the atom is larger in size than calcium atom.

Hence, we can conclude that this element located in Group 2, Period 5 on the periodic table.

Final answer:

The element with two valence electrons and a first ionization energy lower than calcium would be found in Group 2, Period 5 on the Periodic Table.

Explanation:

The element you're referring to, with two valence electrons and a lower first ionization energy than calcium, would be located in Group 2, Period 5 on the Periodic Table.

Here's why: Group 2 elements, or alkaline earth metals, all have two valence electrons. Periods on the other hand, describe the energy level of an atom's outermost electrons, with higher periods corresponding to higher energy levels. Thus, an atom in a higher period would have a lower ionization energy (the energy required to remove an electron) than one in a lower period.

Therefore, because the first ionization energy is lower than calcium (which is in Group 2, Period 4) but still has two valence electrons, this element would be located one period below, in Group 2, Period 5.

Which of the following quantities is the largest?0.00001101 kg
0.001011 g
0.000001101 kg
0.0001011 g

Answers

For this case, the first thing we are going to do is convert all the numbers to the same unit.

For this, we use the following conversion:

1 Kg = 1000 g

We then have the following numbers:

1) 0.00001101 kg = (0.00001101) * (1000) = 0.01101 g

2) 0.001011 g

3) 0.000001101 kg = (0.000001101) * (1000) = 0.001101 g

3) 0.0001011 g

Therefore, the largest amount in grams is:

0.01101 g

Answer:

0.00001101 kg = 0.01101 g

Answers

A) It must be verified by scientists around the world.

A scientific law is a way to describe a phenomenon that occurs in our universe. In order for a research to become law, it must be accepcted by the vast majority - if not all - of the scientists in the same field. However, they do not have to verify the potential law, they can choose to falsify or just to accept proofs taken by the discovers.

A)It has been proven by several scientists independently, resulting in its being accepted as truth.

The Big bang is a scientific theory that explain how our universe was born. Before becoming a theory and becoming the "fact" we assume it is, it was long subject of study, and it was accepted only when different study from different scientists pointed out in the same direction. Hoever, ever today, study continues to have a better understanding of the phenomenon.

D)The results are considered more reliable because they were documented by separate investigations.

When different experiments are made, and they gave out similar results, the results become more reliable, as they are been proven by different sources in an indipendent way. However, this do not imply a pubblication or the trasformation of the results into a scientific law, as those steps go through a different process.

B)nuclear energy

C)electrical energy

D)thermal energy

Only mechanical energy is a type of kinetic energy. Kinetic energy means an energy that derives from a movement. Nuclear energy, electrical energy and thermal energy are other forms of energy. Energy from one of these sources could be converted into kinetic energy, or kinetic energy could be used to generate other forms of energy.

Given the balanced equation representing a reaction:CH4(g) + 2O2(g) --> 2H2O(g) + CO2(g) + heat
Which statement is true about energy in this reaction?
(1) The reaction is exothermic because it releases heat.
(2) The reaction is exothermic because it absorbs heat.
(3) The reaction is endothermic because it releases heat.
(4) The reaction is endothermic because it absorbs heat.

Answers

The answer is (1) the reaction is exothermic because it releases heat. From the reaction, we can see that the heat is at the right of the equation which means the reaction releases heat. So it is called exothermic reaction. Endothermic reaction absorbs heat.

Answer: The answer is (2) the reaction is exothermic because it releases heat.
