In the chemical reaction in which sucrose is heated and decomposes to form carbon dioxide and water a. sucrose is a reactant
Answer:
See below!
Explanation:
A. The picture of the graph is attached. You can tell the amount of protons in an element by looking at the periodic table. The elements are ordered by the number of protons in an element.
B. Carbon and silicon are at the peaks of the chart. The peak is the highest point in a graph.
C. The elements belong to the non-metal group.
D. The halogens are non-metals, and their vapors are colorless.
The halogens are toxic to humans.
Halogen molecules are made of two atoms; they are diatomic.
Halogens react with non-metals to form crystalline compounds that are salts.
The halogens get less reactive going down the group on the periodic table.
Halogens can bleach vegetable dyes and kill bacteria.
E. The picture of the table is attached. To figure which numbers to put where, you need to pay attention to the other numbers. The halogens follow a trend with each of these properties. You have to put in the numbers that fit in among the other numbers.
Answer:
no.
Density (mass / volume) determines whether an object floats or sinks. If the object is less dense than the medium in which it has been submerged, it floats. if it is more dense, it sinks. Volume will definitely determine if a steel ship floats, as steel is far more dense than water.

The mass of an atom and the equivalent of to the number of protons and neutrons in the atom
Answer:
The answer is: phospholipid molecules
Explanation:
The plasma membrane of a cell is consists of a lipid bilayer. This lipid bilayer, also known as the phospholipid bilayer, is a polar membrane composed of two layers of lipid molecules, usually amphipathic phospholipid molecules.
The amphipathic phospholipid molecules have a hydrophilic phosphate head on the exterior and a hydrophobic tail consisting of fatty acid chain on the interior of the membrane.
