Is it true that the salinity of an ocean will increase when a freshwater source flows into it?
False
When salt is dissolved in water the result is a heterogeneous mixture. Is this true or false?
False. It is homogeneous
When magma reaches the surface its dissolved gas content increases True or False?
False! The reduction in pressure causes the gasses to exsolve (come out of solution) and escape into the atmosphere, so the dissolved gas content of a magma reduces when it reaches the surface.
What type of reaaction always has oxygen as a reactant?
false
True or false Hydrogen and oxygen atoms have an equal number of electrons?
False, a Hydrogen has 1 electron and Oxygen has 8 electrons
Is the following sentence true or false the average salinity of seawater is 35 percent?
False. The average salinity of seawater is actually around 3.5%, not 35%.
Is it true that the salinity of an ocean will increase when a freshwater source flows into it?
False
Dissolved salt in ocean water is an example of a chemical change true or false?
false
When sugar is dissolved in water the sugar and water are chemically combined true or false?
False.
In higher pressure environments less gas can be dissolved in a solvent true or false?
False.
When salt is dissolved in water the result is a heterogeneous mixture. Is this true or false?
False. It is homogeneous
Is Salinity the most important factor in the process of photosynthesis true or false?
False. Salinity is not the most important factor in the process of photosynthesis. Light intensity, carbon dioxide concentration, and temperature all play more vital roles in photosynthesis.
Is true plasma contains about 20 dissolved components?
false
Minerals can form from elements dissolved in a solutionTrue or false?
True.
True or false A parity error rarely causes the system to halt?
false it ALWAYS causes the system to halt
When iron rusts iron atoms are destroyed true or false?
False. When iron rusts, iron atoms are not destroyed. Instead, iron atoms combine with oxygen in the presence of water to form iron oxide (rust), which causes the iron to corrode.
Reduction is the gain of oxygen by a metal true or false?
False
