Answer: True
Explanation: They are formed by the cooling and hardening of molten magma
On the off chance that one of the reactants is in overabundance yet you don't know which one it is, you have to compute the hypothetical item mass for the both reactants, with a similar item, and whichever has the lower yield is the one you use to precisely depict masses/sums for the condition, since you can't have more than the non-abundance reactant can create.
Answer:
A process during which chemical bonds between atoms are broken and new ones are formed, producing one or more substances.
Moles are the amount of substance that contains as many particles.
Explanation:
A chemical reaction is when a chemical change occurs for example when a nail comes into contact with air and is then exposed to air it begins to rust. It forms a red-brown substance which changes the chemical composition of the original compound.
Examples of chemical reactions:
Combustion
Oxidation (rusting)
Cooking an egg
Photosynthesis
Digestion
Fireworks
Paper Burnin
The mole is the amount of substance that contains as many particles (molecules, ions or atoms) as there are in 12g of carbon.
1 mol is the amount of substance that contains the same number of particles as there are atoms in 12.0 g of carbon-12 and that number is referred to as Avogardo's constant (6.022 x 
).
Answer;
-The charges of the positive and negative copper ions cancel each other out.
Explanation;
-A normal atom has a neutral charge with equal numbers of positive and negative particles.That means an atom with a neutral charge is one where the number of electrons is equal to the atomic number.
-Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged). If an atom gains or loses one or more electrons, it becomes an ion. If it gains one or more electrons, it now carries a net negative charge, and is thus anionic.
The statement is False.
No, whole cloves are not broken up to help release the eugenol during distillation.
Steam distillation:
- Live steam is used in the co-distillation technique of steam distillation to separate mixture components.
- It works well to extract essential oil constituents with high boiling points, such as those with boiling points of 200°C. However, the oil vapors themselves are warmer—around 100°C—helping to maintain the compounds' structural integrity.
- It enables distillation to be carried out at lower temperatures than the boiling points of the constituent parts.
- The high-boiling essential oils are vaporized by steam, and after passing through a cooling system, the hot vapors that were formed from them condense back into a liquid along with water.
- A two-phase distillate, consisting of a water layer and an oil layer, is created because the oils are immiscible in water.
