Suppose you test a gas in the laboratory. You learn that the gas is made up of carbon atoms and oxygen atoms. Is the gas a compound?

Answers

Answer 1

Answer: Maybe, but she hasn't proved it yet. As another example, somebody may bring a jar of gas to your laboratory, and you test the gas in the jar and you find nitrogen atoms, oxygen atoms, argon atoms, and krypton atoms, and there isn't a single compound in it. The gas in the jar is a MIXTURE of gases . . . a mixture that we call "Air".

Answer 2

Answer: Yes,in chemistry,a compound formed by chemical union of two or more elements or ingredients in definite proportion by weight,for instance,CO2.

Which one of the following parenting factors is associated with improved IQ scores in children? A. Strict discipline
B. Lenient discipline and fewer rules
C. A stable home and varied activities
D. Early instruction in reading

Answers

Answer: Option (C) is the correct answer.

Explanation:

The term IQ stands form intelligent quotient. When a child is provided with stable home environment in which there are less or rare conflicts, happy environment, understanding between individuals etc will lead to a stable growth of child.

Also, varied activities will help child to learn quickly and develop various skills.

Thus, a stable home and varied activities is the one parenting factor which is associated with improved IQ scores in children.

The correct answer is C. A stable home and varied activities.

Suppose you discovered a new element with 120 protons and 2 electrons in its outer lever. In what group does this new element belong

Answers

Answer:

This new element belongs to the group 2.

Explanation:

In the periodic table, the vertical columns are called groups (or families). The elements in the same group share similar chemical and physical properties.

One of these properties is the same amount of outer valence electrons.

For example, in the group 1 the elements have 1 outer valence electron (If we assume that the element is in a neutral state which is without electrical charges).

If this new element has 2 electrons in its outer level it will belong to the group 2. The group 2 is well-known as alkaline earth metals.

For example, the magnesium (Mg) and the calcium (Ca) belong to the group 2.

Assuming the 2 valence electrons are of the neutral state of the new element, the element would belong in Group 2, the Alkaline Earth Metals.

Answers

The answer is current.

Current in the context of an electrical circuit is the flow of charge. Current is a quantity that is physical and can be measured. Current is defined as the rate of the flow charge past a certain point in a circuit. Current is expressed in Amperes which is equal to 1 coulomb/1second.
