What is the volume of 40g of sugar given it’s listed density
lora16 [44]

Answer:

25.157 cm³

Explanation:

Data Given:

Mass of Sugar (m) = 40g

Density of sugar given in literature = 1.59 g/cm³

Volume of Sugar = ?

The formula will be used is

                              d = m/v ........................................... (1)

where

D is density

m is the mass

v is the volume

So

Rearrange the Equation (1)

                              d x v = m

                               v = m/ d         ................................................ (2)

put the given values in Equation  (2)

                       v = 40g / 1.59 g/cm³

                       v = 25.157 cm³

volume of 40 g of sugar = 25.157 cm³

How do modern scientists describe the makeup of matter?
zavuch27 [327]
Any substance made out of iotas, that has mass and possesses space. Matter ought not be mistaken for mass, as the two are not the same in current material science. Matter is itself a physical substance of which frameworks might be formed, while mass isn't a substance but instead a quantitative property of issue and different substances or frameworks. While there are diverse perspectives on what ought to be viewed as issue, the mass of a substance or framework is the same regardless of any such meaning of issue. Another distinction is that issue has an "inverse" called antimatter, however mass has no inverse—there is no such thing as "hostile to mass" or negative mass. Antimatter has the same (i.e. positive) mass property as its typical issue partner.

1. Consider the following equilibrium system: C(s) + CO2(g) 2CO(g)
ser-zykov [4K]

Answer:

a) equilibrium shifts towards the right

b) equilibrium shifts towards the right

c) equilibrium shifts towards the left

d) has no effect on equilibrium position

e) has no effect on equilibrium position

Explanation:

A reversible reaction may attain equilibrium in a closed system. A chemical system is said to be in a state of dynamic equilibrium when the rate of forward reaction is equal to the rate of reaction.

According to Le Chateliers principle, when a constraint such as a change in temperature, pressure, volume or concentration is imposed upon a system in equilibrium, the equilibrium position shifts in such a way as to annul the constraint.

When the concentration of reactants is increased, the equilibrium position is shifted towards the right hand side and more products are formed. For an endothermic reaction, the reverse reaction is favoured by a decrease in temperature. Increase in pressure has no effect on the system since there are equal volumes on both sides of the reaction equation. Similarly, the addition of a catalyst has no effect on the equilibrium position since it speeds up both the forward and reverse reactions to the same extent.
