Elements that are metals tend to lose electrons and become positively charged ions called cations. Elements that are nonmetals tend to gain electrons and become negatively charged ions called anions. So, if you are asking would hydrogen most likely gain electrons the answer would be yes it would gain electrons.

Representative elements are grouped according to which of the following?

sdas [7]

B. Representative electrons

Firstly it is best to describe the shape and structure of an atom, an atom's system and structure is like of the solar planet, the heliocentric view where the sun is the neutrons and protons and the planets are the electrons. Moreover, the electrons are outside these neutrons and protons surrounding the entire system of its atomic structure. Its movement is like of a planet.

An energy level also known as electron shell, or just shell is a location around an atom where electrons with a specific energy value, or quantum number may be found.

Which statements are true? Δ???? for an exothermic reaction is positive. Δ???? for an endothermic reaction is positive. The evap

LuckyWell [14K]

Answer: The true statements are $\Delta H$ for an endothermic reaction is positive, a combustion reaction is exothermic and when energy is transferred as heat from the system to the surroundings, $\Delta H$ is negative.

Explanation:

There are 2 types of chemical reactions categorized into heat change:

Endothermic reactions: These reactions are defined as the reactions in which energy is absorbed by the system from the surroundings. The $\Delta H$ for these reactions is always positive. For Example: Changing of water into water vapor.
Exothermic reactions: These reactions are defined as the reactions in which energy is released by the system to the surroundings. The $\Delta H$ for these reactions is always negative. For Example: Combustion reactions.

Combustion reactions are defined as the reactions in which a hydrocarbon reacts with oxygen gas to produce carbon dioxide and water. Heat is released during these reactions. Thus, it is considered as exothermic reactions.

Hence, the true statements are $\Delta H$ for an endothermic reaction is positive, a combustion reaction is exothermic and when energy is transferred as heat from the system to the surroundings, $\Delta H$ is negative.

Although expensive, platinum is used as a catalyst to break down harmful gases in car exhaust into less harmful gases. Which sta

Dimas [21]

Platinum is solid at room temperature. SInce the catalyst is solid while the medium involves gases, this catalyst is characterized as heterogenous. Because they are different states of matter, they can be easily separated through physical means. So, the answer is B.

What are the components needed in order for an experiment to be valid? Identify these components in the following experiment: A

VMariaS [17]

He is missing a (real) control. Growing two plants without plant food at all doesn't count; in order to see if the new food is better, he must also grow plants with the original food in order to compare it.

He does have an independent variable. This is the type of plant food. It's independent because he has direct control over it.

He needs to give plants the same conditions besides food: same water (amount), same light exposure, same temperature, etc.

He needs to choose a quantitative way to measure how much the plants grew, like mass or length.
