Answer:
Inside it's usually warm so when you open a door to outside which is cold a cold front and a warm front will be exposed to each other cold will win usually since cold goes below the warm front.
Explanation:
Moles of ZnSO4 = Mass/Mr
= 2/(65.4 + 32.1 + (16 x 4))
= 0.012383.... mol
Since there is no chemical equation provided, I will assume that the ratio of ZnSO4:Li2CO3 is 1:1
Therefore there are 0.012383 mil of Li2SO4 as well
So the mass would be Moles x Mr = 0.012383.... x ((6.9 x 2) +32.1 + (4x16))
= 1.360 g of Li2SO4 produced
Answer is: <span>because dissolved compounds can crystallizing from solution during filtration and forming crystals on the filter paper or funnel.
</span>Recrystallization<span> is a technique used to purify chemicals by dissolving both impurities and a compound in an appropriate solvent, either compound or impurities can be removed from the solution, leaving the other behind.</span>
Answer: A. The particles move faster
Explanation:
Increasing the temperature increases the kinetic energy of the particles, causing them to move faster.
Answer:
Genes are contained in chromosomes, which are in the cell nucleus. A chromosome contains hundreds to thousands of genes. ... A trait is any gene-determined characteristic and is often determined by more than one gene. Some traits are caused by mutated genes that are inherited or that are the result of a new gene mutation.
