draw the major and minor product when the following alkyl halide is heated with sodium ethoxide in ethanol. you may neglect cis-trans isomerism of the products when answering this question. if there is only one product, click no reaction for the minor product.
The major product is 3-methyl-2-pentene and the minor product is 2-ethyl-1-butene.
The alkyl halide shown is 3-bromo-3-methyl pentane. We can see that it is a tertiary alkyl halide. The proportion of products formed during the reaction are determined by Markovnikov rule.
The two products of this reaction are; 3-methyl-2-pentene and 2-ethyl-1-butene. The major product is 3-methyl-2-pentene because it is formed from a more stable carbocation intermediate. 2-ethyl-1-butene is the minor product.

Butene gas C4H8 has a molar mass of 56.1gmol. If it occupies 3000. mL of space at 1000. K and 760. torr, how much butene gas (in grams) is present
Answer:
2.05g
Explanation:
The weight of butane gas present in the system with the specified temperature and pressure is 2.05 g. We can use ideal gas law here.
What is ideal gas law?Ideal gas law states the relation between temperature, pressure and volume and mathematically written as below:
PV = nRT
Here, P and V be the pressure and volume and n be the no.of moles and R be the universal gas constant. T is the absolute temperature in kelvin.
The system have a volume of 3000 mL or 3 L and pressure of 760 torr and temperature of 1000 K. The no. of moles n is the ratio of taken weight to the molar mass. R has the value 62.36 L torr/(K mol)
Apply these values into ideal gas law as given below:
(3 L × 760 torr) = (w/56.1 g/mol) × 62.36 L torr/(K mol) × 1000 K. From this,
[tex]2280 \textup{ torr L} = \frac{w}{56.1 g/mol} \times 62360 \textup{ L torr/mol}[/tex]
[tex]w = \frac{2280\textup{ torr L}\times 56.1\textup{ g/mol}}{62360 \textup{ L torr/mol}} =2.05 g[/tex]
Therefore, the amount of butane gas for the given system is 2.05 g.

3. How many grams of magnesium ion are in 155.0 grams of Mg3P2?
Answer:
83.82 g of magnesium ions.
Explanation:
We want to determine the mass of magnesium ions in 155.0 grams of magnesium phosphide (Mg₃P₂).
We can convert from grams of Mg₃P₂ to moles of Mg₃P₂, moles of Mg₃P₂ to moles of Mg, and moles of Mg to grams of Mg.
Find the molecular weight (molar mass) of magnesium phosphide:
[tex]\displaystyle \begin{aligned}\text{MW}_\text{Mg$_3$P$_2$} &= \left(3(24.31)+2(30.97)\right) \text{ g/mol} \\ \\ &= (72.93 + 61.94) \text{ g/mol} \\ \\ &= 134.87 \text{ g/mol}\end{aligned}[/tex]
The molecular weight of magnesium is 24.31 g/mol*.
From the chemical formula, we can see that there are three moles of magnesium for every one mole of magnesium phosphide.
Hence, multiply initial amount with known ratios:
[tex]\displaystyle \begin{aligned} &155.0 \text{ g Mg$_3$P$_2$} \cdot \frac{1 \text{ mol Mg$_3$P$_2$}}{134.87\text{ g/mol}} \cdot \frac{3\text{ mol [Mg$^{2+}$]}}{1 \text{ mol Mg$_3$P$_2$}}\cdot \frac{24.31 \text{ g [Mg$^{2+}$]}}{1 \text{ mol [Mg$^{2+}$]}}\\ \\ & = 83.82 \text{ g [Mg$^{2+}$]}\end{aligned}[/tex]
In conclusion, there are 83.82 grams of magnesium ions in 155.0 grams of magnesium phosphide.
*Because the magnesium ions in magnesium phosphide have two less electrons, its molecular weight will indeed be lower. However, due to the extremely small size of an electron (1/2000th of a proton), the difference in mass is insignificant.

Organisms that reproduce sexually have offspring with greater variety. Which statement best explains this characteristic?
A. The offspring get DNA from two parents, and it mutates regularly.
B. The offspring get DNA from two parents, and it combines randomly.
C. The offspring get DNA from one parent, and it mutates regularly.
D. The offspring get DNA from one parent, and it combines randomly.
Organisms that reproduce sexually have offspring with greater variety because: B. The offspring get DNA from two parents, and it combines randomly.
Reproduction refers to a biological process through which living organisms (parents) mate to produce offspring.
Basically, there are two (2) main types of reproduction and these include;
Asexual reproduction.Sexual reproduction.During sexual reproduction, parent organisms produce offspring with greater variety because the genetic material of their parents are randomly combined to produce genetically-diverse offspring.

I need help please! Describe how distillation works using the terms boiling and condensation?
Answer:
it boils a liquid to create condomsation
Explanation:
Answer:
Distillation refers to the selective boiling and subsequent condensation of a component in a liquid mixture. It is a separation technique that can be used to either increase the concentration of a particular component in the mixture or to obtain (almost) pure components from the mixture. The process of distillation exploits the difference in the boiling points of the components in the liquid mixture by forcing one of them into a gaseous state.

Analyze how humans use technology to store (potential) and/or use (kinetic) energy.*
Science btw
Human devices use potential energy to store energy, whereas kinetic energy is potential energy in motion. Both types of energies can be measured in Joules (J).
Human devices generate and use different sources of energy, which can be classified into renewable sources (e.g., solar, hydraulic, winds, etc) and non-renewable sources (e.g., nuclear energy) of energy.
For example, a hydroelectric power plant transforms the potential energy stored in water reservoirs (e.g., a lake) into mechanical energy (a type of kinetic energy) when this energy is released from the water reservoir and flows through a turbine.
Subsequently, this type of kinetic energy is then used to generate electricity.
On the other hand, a nuclear power plant uses the potential energy that is stored within the nuclei of atoms to produce kinetic energy by a process known as nuclear fission.
This process (nuclear fission) releases energy in the form of heat (i.e., thermal energy).
Subsequently, this type of kinetic energy (heat) is used to generate steam, which then moves turbines to generate mechanical energy and finally generates electricity.
