Answer:

Bromine water test

There are two tests to detect the presence of unsaturated double bond in an organic molecule, the bromine water test and Bayer's test. In the bromine water test, when the molecule is added to bromine water, bromine is added to the carbon atoms across the double bond.

How does the activity series of metals tell which reactions will occur?

Helga [31]

C. Metals higher in the series will replace metal ions in solution that

are lower in the series.

Explanation:

The activity series of metals shows the extent of reactivity of different metals.

On the activity series, the most reactive metals are located higher up on the able whereas the less reactive ones are found at the bottom of the series.

We can tell if single displacement reactions will occur by simply looking at the reactivity series.
Metals that are more reactive will displace the ones that are not very reactive that are positioned down the series. Such a reaction will occur.
Metals lower in the series cannot displace the ones on top because they are less reactive. Such a reaction will not occur.

As a Ca atom undergoes oxidation to Ca2+, the number of neutrons in its nucleus

maria [59]

Oxidation refers to a change in electrons (In this case, loss of electrons). It has no impact on the number of neutrons, or for that matter on any sub-atomic particles in the nucleus. So the number of neutrons (3) remains the same

Nonmetals rarely lose electrons in chemical reactions because?

ziro4ka [17]

The reason for this is because nonmetals, have close to fulfilling an octet and need to gain few more electrons to do this, not to lose more. Nonmetals, because of the fact they need only few more electrons to satisfy their octet they would receive or share electrons to do this.

The property that nonmetals have are that they are very electronegative, they possess a strong affinity to pull electron density closer, because they possess fewer electron shells and possess even protons this allows for this.

Two identical containers, one red and one yellow, are inflated with different gases at the same volume and pressure. Both contai

Evgen [1.6K]

Answer:

Explanation:

Here we're dealing with the root mean square velocity of gases. We'll provide the formula in order to calculate the root mean square velocity of a gas:

$v_{rms}=\sqrt{\frac{3RT}{M}}$

Here:

$R = 8.314 \frac{J}{K mol}$ is the ideal gas law constant;

$T$ is the absolute temperature in K;

$M$ is the molar mass of a compound in kg/mol.

We know that the gas from the red container is 4 times faster, as it takes 4 times as long for the yellow container to leak out, this means:

$\frac{v_{rms, red}}{v_{rms, yellow}} = 4$

We also know that the temperature of the red container is twice as large:

$\frac{T_{red}}{T_{yellow}} = 2$

Write the ratio of the velocities and substitute the variables:

$\frac{v_{rms, red}}{v_{rms, yellow}}=\frac{\sqrt{\frac{3RT_{red}}{M_{red}}}}{\sqrt{\frac{3RT_{yellow}}{M_{yellow}}}}=4$

Then:

$\frac{\sqrt{\frac{3RT_{red}}{M_{red}}}}{\sqrt{\frac{3RT_{yellow}}{M_{yellow}}}}=\sqrt{\frac{3RT_{red}}{M_{red}}\cdot \frac{M_{yellow}}{3RT_{yellow}}}=\sqrt{\frac{T_{red}}{T_{yellow}}\cdot \frac{M_{yellow}}{M_{red}}}=4$

From here:

$16 = \frac{T_{red}}{T_{yellow}}\cdot \frac{M_{yellow}}{M_{red}}$

Then:

$\frac{M_{yellow}}{M_{red}} = \frac{16}{\frac{T_{red}}{T_{yellow}}} = \frac{16}{2} = 8$
