What is the best grade of gold? So, which one is the best? 24k, 22k, 18k, or 14k? 24K (100% pure gold) Being the highest karat of gold, it’s easy to assume that 24K is the “best” gold to buy, but that isn’t necessarily the case. 22K (92% gold and 8% alloyed metals) 18K (75% […]
How is the rate of reaction affected if the concentration of A is doubled?
How is the rate of reaction affected if the concentration of A is doubled? The rate is proportional to the concentration of a reactant. When you double the concentration the rate doubles. The rate is proportional to the square of the concentration of a reactant. When you double the concentration the rate goes up four […]
Is a nuclear explosion a chemical reaction?
Is a nuclear explosion a chemical reaction? Chemical explosions are chemical reactions in which only the atom’s electrons are involved. Nuclear explosions involve bonds between protons and neutrons inside the nuclei of the atoms. An atom consists of elementary particles called protons and neutrons, which are tightly bound within a nucleus. Are nuclear reactions affected […]

Are plants made from thin air?
Are plants made from thin air? Plants Are Made from Thin Air? CO, from the air gets incorporated into a glucose molecule. Then, the glucose molecule becomes part of the plant. Plants make their own food – a sugar molecule called glucose Water molecules and carbon dioxide molecules are combined to produce sugar molecules (glucose). […]
