Answers

Based on the duration and effect of the environmental change, the correct categorization is as follows:

Short-term changes - Fire, flood, pollution of waterways, disease Long-term changes- extinction, early frost, deforestation, desertification

What are environmental changes?

Environmental changes refers to changes that occur in the environment either due to natural causes or by human activities.

Environmental changes can be categorized into:

short-term changes andlong-term changes

Short-term changes occur over a short period of time while long-term changes occur over a long period of time.

Based on the chart, the correct categorization is as follows:

Short-term changes - Fire, flood, pollution of waterways, disease Long-term changes- extinction, early frost, deforestation, desertification

Therefore, both long-term and short-term changes occur in the environment.

What is the ph of a solution of h2so4 that has [h3o ] = 5.45 × 10–5 m? round to the nearest hundredth.

Answers

The pH of a solution of H₂SO₄ that has [H₃O⁺] is 5.45 × 10⁻⁵ M, is 4.26.

What is pH?

pH is define as the negative logarithm of the concentration of H⁺ or H₃O⁺ ions, and it is represented as:

pH = -log[H⁺]

Concentration of H₃O⁺ in H₂SO₄ solution = 5.45 × 10⁻⁵ M

pH of H₂SO₄ solution will be calculated as:

pH = -log(5.45 × 10⁻⁵)

pH = -(-4.26)

pH = 4.26

Hence required pH is 4.26.

How much hcl must be added to a liter of buffer that is 1. 5 m in acetic acid and 0. 70 m in sodium acetate to result in a buffer ph of 4. 01?]

Answers

For a liter of a buffer that is 1. 5 m in acetic acid and 0. 70 m in sodium acetate, and with a result in a buffer pH of 4.01, the moles of HCl required is mathematically given as x=0.313mol

What is the result in a buffer ph of 4. 01?

Generally, the equation for the pH is mathematically given as

pH=pKa+logsalt/acid

Generally, the equation for the Chemical Reaction is mathematically given as

HCl+CH3CooNa---->NaCl+CH3OOH

Therefore

4.01=4.74+log\frac{0.8-x}{1.3+x}

-0.52=log\frac{0.8-x}{1.3+x}

x=0.313mol

In conclusion, The moles of HCl required is

x=0.313mol

Answer:

When radioactive atoms decay, they release energy in the form of ionizing radiation (alpha particles, beta particles and/or gamma rays). The energy is called ionizing radiation because it has enough energy to knock tightly bound electrons from an atom's orbit. This causes the atom to become a charged ion.

What causes “gaps in the rock record” and how is that described?

Answers

Answer:

An unconformity is a widespread surface separating rocks above and below, which represents a gap in the rock record. Unconformities occur when either erosion wears away rocks, or rock deposits never form. Therefore, a time gap exists between when the rocks below the unconformity formed and when those above it formed.

Which hydrogen of 1-chloropent-2-ene shows the largest chemical (downfield) shift in its nmr spectrum?

Answers

The hydrogen of 1-chloropent-2-ene shows the largest chemical shift is C2 or C3 because they are more de-shielded than they have the largest chemical shift value.

Which hydrogen of 1-chloropent-2-ene shows the largest chemical shift in its nmr spectrum?

Generally, There is the biggest chemical shift at C2 or C3 due to the fact they are connected through the pi- bond and range is about 4.5 - 6 ppm and C1 has a range of about 3.5 due to Cl- ion.

In conclusion, C2 or C3 is more de-shielded than they have the largest chemical shift value.
