Difference Between baking soda and baking powder
Answer:
Baking soda is sodium bicarbonate, which requires acid and a liquid to become activated and help baked goods rise. Conversely, baking powder includes sodium bicarbonate, as well as an acid. It only needs a liquid to become activated. Substituting one for the other is possible with careful adjustments. Baking soda is strong. In fact, it is about 3-4x stronger than baking powder. More baking soda in a recipe doesn't necessarily mean more lift.
Explanation:
Explanation:
baking soda contains one ingredient, sodium bicarbonate. however, baking powder contains sodium bicarbonate , monocalcium phosphate and either sodium acid prophetess or sodium aluminum sulfate

what is the trend for atomic radii across the periods and down the group?
Answer:
So, in general, atomic radius decreases across a period and increases down a group. Across a period, effective nuclear charge increases as electron shielding remains constant.
Explanation:
Moving from left to right across a period, the atomic radius decreases. The nucleus of the atom gains protons moving from left to right, increasing the positive charge of the nucleus and increasing the attractive force of the nucleus upon the electrons.

What two things do astronomers need to know about a star in order to calculate its luminosity or absolute magnitude? A.color and size B.color and distance C.distance and brightness D.size and distance
(đ) is answer of question.
Explanation:
However, the brightness of a star depends on its composition and how far it is from the planet. Astronomers define star brightness in terms of apparent magnitude — how bright the star appears from Earth — and absolute magnitude — how bright the star appears at a standard distance of 32.6 light-years, or 10 parsecs.
MARK ME AS A BRAINLIST PLZ
Astronomers measures the luminosity of stars by determining the magnitude of brightness and distance from earth.Thus option C is correct.
What is luminosity?Luminosity of a star is the total amount of energy radiated by them to a distance. The luminosity vary from star to star based on the distance to them.
Luminosity is basically measured in terms of brightness as observed from the earth. Stars will make a group in certain shapes and certain number called constellation. The overall brightness can be then higher for each constellation.
Astronomers define the brightness of stars by the apparent distance from the earth whereas the absolute magnitude is defined is terms of standard distance of 32.6 light years. Hence, the option C based on distance and brightness is correct.

The correct name of the compound CuCl is copper I chloride.
An ionic compound is formed two atoms when one loose electrons and the other atoms gains those electrons. Ionic bonds are actually an ion pair, a pair of oppositely charged ions held together by electrostatic interaction. Transition metals are elements with incompletely filled d orbitals. Copper is a transition element.

The mass lost by the positive electron should equal the mass gained by the negative electrode suggest two reasons why the results were not expected.
Answer:
The gain in mass by the negative electrode is the same as the loss in mass by the positive electrode. So the copper deposited on the negative electrode must be the same copper ions that are lost from the positive electrode.

where do the electrons that are excited by the energy in sunlight first come from?
Answer:
Pigments in the light-harvesting complex pass light energy to two special chlorophyll a molecules in the reaction center. The light excites an electron from the chlorophyll a pair, which passes to the primary electron acceptor. The excited electron must then be replaced.
Explanation:
During photosynthesis,the electrons that are excited by the energy in sunlight first come from chlorophyll pigment present in the leaves.
What is photosynthesis?It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy through the process of cellular respiration.
Some of the energy which is converted is stored in molecules of carbohydrates like sugar and starches which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.
The process begins with proteins absorbing light energy which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.
