Explanation:

NiCl2 + KOH = NiOH + KCl

since nickel is the primary element in nickel ii chloride, find the oxidation no of nickel in the compound and chlorine should have 2 as a subscription since the ii in the compound represents that nickel has an oxidation no of 2

How might an increasing population of robins positively and negatively affect a community?
Oliga [24]

All populations of living things are interrelated. When one population of animals, plants, or insects increase or decrease, other populations of living things are also affected. For example, when shrubs and brushy areas are removed from an ecosystem, the rabbit population will likely go down. The reduced rabbit population will lower predator populations that use rabbits as a food source.

In another example, let's assume all the dead hollow trees are removed from a forest ecosystem. Cavity nesting animals such as bluebirds, nuthatch, wrens, screech owls, squirrels and woodpeckers have very little, if any, shelter available. The number of animals of this type would be reduced. Insect populations could increase because of fewer insect eating birds and trees and other plants could be negatively affected. The whole ecosystem is affected.

The amount of suitable habitat for a species of wildlife will determine the number of animals that can survive in the area. Human activity has the greatest impact on the amount and quality of wildlife habitat in Illinois. Wildlife habitat can be destroyed or its quality diminished as a result of urban sprawl, agricultural practices, pollution, sedimentation, or habitat fragmentation.

People can also have a positive impact on wildlife populations through improvement and protection of habitat or ecosystems. The planting of trees and shrubs, as well as wildlife food plots, in the appropriate locations is one way landowners can improve wildlife habitat. People can protect ponds, streams, rivers and wetlands from sedimentation by reducing soil erosion on lands surrounding these aquatic ecosystems. Nesting boxes placed in ecosystems that lack dead, hollow trees will enhance the habitat for cavity nesting animals. There are many things people can do to improve habitat for wildlife.

There are a number of natural resource management agencies in Illinois that can help people enhance and protect wildlife habitat. Listed below are a few of the public agencies which can provide ecosystem management expertise to people in Illinois.

In an acid-base neutralization reaction 38.74 ml of 0.500 m potassium hydroxide reacts with 50.00 ml of sulfuric acid solution.
DaniilM [7]

Answer:

0.2 M.

Explanation:

  • For the acid-base neutralization, we have the role:

The no. of millimoles of acid is equal to that of the base at the neutralization.

<em>∴ (XMV) KOH = (XMV) H₂SO₄.</em>

X is the no. of reproducible H⁺ (for acid) or OH⁻ (for base),

M is the molarity.

V is the volume.

  • For KOH:

X = 1, M = 0.5 M, V = 38.74 mL.

  • For H₂SO₄:

X = 2, M = ??? M, V = 50.0 mL.

∴ M of H₂SO₄ = (XMV) KOH/(XV) H₂SO₄ = (1)(0.5 M)(38.74 mL)/(2)(50.0 mL) = 0.1937 M ≅ 0.2 M.

What is the shape pf a molecule with a triple bond
makkiz [27]

Explanation:

A molecule with a triple bond will have a linear geometry as the angles between the bonds will be 180 degrees. Hence, it will be a linear geometry.

For example, a molecule of dinitrogen (N_{2}) has nitrogen atoms bonded through triple bond as follows.

                                      :N ≡ N:

Since valency of nitrogen is 5 therefore, each nitrogen will have one lone pair of electrons.

How does an atom become charged?
inessss [21]

Answer:

An atom becomes charged when there is an unequal amount of positive and negative particles in the nucleus.

An atom gets a positive charge when there is an increase in protons or a decrease in electrons, such that there are more protons than electrons in the nucleus.

An atom gets a negative charge when there is an increase in electrons or a decrease in protons, such that there are more electrons than protons in the nucleus.

An atom can get a charge with a change of particles in the nucleus if that change results in an uneven number of protons and electrons.

Explanation:

Because protons are positively charged particles and electrons are negatively charged particles, a neutral atom has an equal amount of protons and electrons, so that the opposite charges of the particles cancel each other out.

However, if there is an unequal amount of protons or electrons in the nucleus, the charge of the particles will no longer be canceled out, and the atom as a whole will take on a positive or negative charge.
