Answer:
So if this is about chemical equations. You have 3 steps.
Step 1.- Count each type of atom in reactants and products.
Step 2.- Place coefficients, as needed, in front of the symbols or formulas to increase the number of atoms or molecules of the substances.
Step 3.-Repeat steps 1 and 2 until the equation is balanced.
Explanation:
The element is americium, a metal from the actinides. The element is in Period 4 and Group 2. Even though the 4s sublevel is filled, the last electron went into that sublevel, making it a member of the s-block. It has 2 valence electrons.
Answer:
Calcium chloride cannot melt the ice at -20°C. Cryoscopy is the method of determining a decrease in melting point due to dissolved substances.
Answer:
See the answer below
Explanation:
Plants grow in many different shapes and sizes. Much of their shape depends on an internal structure that is composed of carbon-containing molecules such as cellulose and lignin. Plants that have a strong internal structure can grow larger than other plants because their structure can support their size. Plants obtain the majority of the carbon necessary for building these structural molecules from <u>carbohydrates that are synthesized during photosynthesis.</u>
<em>Plants obtain carbon to build their structures by a process known as carbon fixation or photosynthesis. During this process, inorganic carbon in the form of carbon dioxide reacts with water to produce carbohydrate. Radiant energy from the sun is required for the process to go into completion and oxygen is released as a by-product. The entire process can be summarized by the following equation:</em>
