<span>A cement is a binder. It is a substance that sets and hardens and can bind other materials together. Cement is usually in a form of powder which is being mixed with other materials and water. The most important uses of cement are as a component in the production of mortar in masonry, and of concrete, a combination of cement and an aggregate to form a strong building material. Cements used in construction can be characterized as being either hydraulic or non-hydraulic, depending upon the ability of the cement to set in the presence of water.</span>

What happened to the rate of the reaction when the concentration was increased?

pickupchik [31]

Answer:

If you increase the concentration of a reactant, there will be more of the chemical present. More reactant particles moving together allow more collisions to happen and so the reaction rate is increased. The higher the concentration of reactants, the faster the rate of a reaction will be.

Answer:
FOUR <span>asymmetric centers are present in the open chain form of the Aldohexose d-(-)-Gulose.

Explanation:
Here the word Asymmetric center means those carbon atoms which contains atoms or group of atoms different from each other. All the four atoms or group of atoms attached to carbon atom are different and have different molecular masses. Such carbon atoms are also called as Chiral carbons. The structure of </span>d-(-)-Gulose is drawn below, and all Four Asymmetric centers are pointed by " * "

11.27 mol of carbon dioxide gas is equal to how many liters

saw5 [17]

11.27 mol of carbon dioxide gas is equal to 252.45 L or 270.48 L

<h3>Further explanation</h3>

Given

11.27 mol of CO2

Required

Volume of gas

Solution

If the conditions are assumed to be at the STP state (Standard Temperature and Pressure) at T 0 ° C and P 1 atm, then Vm is 22.4 liters/mol.

so for 11.27 moles the total volume is:

11.27 mol x 22.4 L = 252.45 L

But if the conditions are assumed to be at RTP (Room Temperature and Pressure), Conditions at T 25 ° C and P 1 atm. Vm = 24 liters/mol, then the volume of CO2:

11.27 mol x 24 L = 270.48 L.
