I believe that an insoluble solid that forms a chemical reaction is called a precipitate.
Precipitate is an insoluble solid that forms when two ionic compounds in solution are combined. Which means precipitation reaction is the creation of a solid from a solution, and when the reaction occurs in a liquid solution, the solid formed is called the precipitate. In fact the only method of forming insoluble salts is called precipitation or double decomposition of salts.
The climatology method of forecasting uses averages to predict future weather.
Answer: B
Explanation
The satellites and advanced technologies have helped meteorologists to forecast accurately.
There are four types of forecasting methods prevailing now.
They are climatology method, persistence method, analog method and trends method.
The persistence and trends method uses the previous day forecast and compare with today's condition to forecast about future.
The analog method is a complex method where the forecasting is done by comparing present weather condition with a similar condition occurred in the past to predict for future.
The climatology is the simplest method which uses average of weather conditions observed in the previous days to get accurate forecast for future.
Answer:
grapefruit juice is an acid
Explanation:
A piece of neutral litmus paper turned red in some grapefruit juice. What does this show about the grapefruit juice
with litmus paper remember:
E R
S E
ACID
BLUE
acids turn litmus red, bases turn it blue
all citrus fruits :llemons, lime, grapefruit, oranges, etc are called
CITRUS FRUITS because they contain citric acid
The molarity of the HCl is 1 M when 12.0 of .500 M NaOH neutralized 6.0 ml of HCl solution.
Explanation:
Data given:
molarity of the base NaOH, Mbase =0. 5 M
volume of the base NaOH, Vbase = 12 ml
volume of the acid, Vacid = 6 ml
molarity of the acid, Macid = ?
The titration formula for acid and base is given as:
Mbase Vbase = Macid Vacid
Macid =
Macid = 1 M
we can see that 1 M solution of HCl was used to neutralize the basic solution of NaOH. The volume of NaOH is 12 ml and volume of HCl used is 6ml.
Answer:
In the chemical bonds.
Explanation:
There are different types of chemical bonds, some store a TON of energy while others do not store as much. You can think of it like this: for bonds with low energy, it takes a LOT of force to pull them apart, meaning they are strong bonds. However, this way, you have to put energy into them to break the bonds and form a chemical reaction. This is an endothermic reaction, a reaction that absorbs heat from its surroundings.
Instead, bonds in exothermic reactions are BEGGING to form a more stable bond, and hence store a lot of potential energy. Due to the difficulty of maintaining these bonds, there is a lot of energy put into them. If you break them, however, (exothermic reaction) the energy is released, and hence the exothermic reaction happens.
