Which element is capable of forming long chains by forming single, double, or triple bonds with itself?

Answers

the answer is carbon

Catenation is the property by which it can make bonds with other carbon atoms to form long chains. Hence, carbon, with the least diffuse valence shell p orbital is capable of forming longer p-p sigma bonded chains of atoms than heavier elements which bond via higher valence shell orbitals.

Which of the following is NOT a method of transferring heat?a. convection
c. reduction
b. radiation
d. conduction

Answers

The answer is Reduction. All three methods (convection, radiation, and conduction) are all ways of transferring heat. Convection is the transfer of heat by means of a medium such as air. Conduction is the transfer of heat from the contact of two surfaces at different temperatures. Radiation is the transfer of heat via electromagnetic waves.

Reduction is a chemical reaction that involves the gain of electrons. It is the opposite of oxidation which involves the loss of electrons.

Answer: 22) < 24) 0.003 30,000 25) 1 cc = 1 ml

Explanation:

When give a number in scientific notation, the exponent tells you how many places to move the decimal point.

Negative moves to the left.
Positive moves to the right.

$22)\ 5* 10^(-4)=0.0005\quad \longrightarrow 0.0005<1.0$

$24)\ 3* 10^(-4)=0.0003\qquad \qquad 3* 10^4=30,000$

25) 1 cubic centimeter (cc) = 1 milliter (ml)

The conversion factor is 1 to 1. You just need to change cc to ml

When conducting an experiment, a scientist should: (a) attempt to test every possibility (b) attempt to control the conditions (c) place no limits on the investigation (c) proceed without specific goals

Answers

Answer : Option B) Attempt to control the conditions.

Explanation : While conducting an experiment, a scientist should always attempt to control the reaction conditions.

If the reaction conditions are not controlled one can lose the expected result or observation that was supposed to be generated from the experiment. Like controlling the given temperature, pressure, addition of catalysts, etc. If these conditions are overlooked one may not achieve the expected results and will not reach to the conclusion.

B attempt to control the conditions

How do you draw a bohr diagram for a boron ion? Some backgorund info: (of boron atom)
Atomic no- 5
Mass no- 11
Cation

Answers

Because Boron likes to lose 3 electrons when it undergoes ionization, we draw a boron ion like a helium atom, with just 2 electrons in the first shell, and 0 in the second
