Which type of bond is present within a water molecule

1. Describe the evidence that stress plays a role in the development of schizophrenia.

valentina_108 [34]

Answer:

Research shows that patients with schizophrenia are more affected by stress physically as well as emotionally, for instance they show different changes in heart rate under stress and a greater overall risk of cardiovascular disease.

The empirical formula of an organic compound is C2H4O. The molecular mass of the compound is 176g/mol.

Brrunno [24]

Answer:

The molecular formula of the compound is $C_{8}H_{16}O_{4}$ . The molecular formula is obtained by the following expression shown below

$\textrm{Molecular formula }= n\times \textrm{Empirical formula}$

Explanation:

Given molecular mass of the compound is 176 g/mol

Given empirical formula is $C_{2}H_{4}O$

Atomic mass of carbon, hydrogen and oxygen are 12 u , 1 u and 16 u respectively.

Empirical formula mass of the compound = $\left ( 2\times12+4+16 \right ) \textrm{ u} = 44 \textrm{ g/mol}$

$n = \displaystyle \frac{\textrm{Molecular formula mass}}{\textrm{Empirical formula mass}} \\n = \displaystyle \frac{176}{44} = 4$

$\textrm{Molecular formula }= n\times \textrm{Empirical formula}$

Molecular formula = 4 $\times$ $C_{2}H_{4}O$

Molecular formula is $C_{8}H_{16}O_{4}$

Practice Problem 12.39 Partially correct answer. Your answer is partially correct. Try again. Acid-catalyzed hydration of 1-meth

Zielflug [23.3K]

Answer:

See explanation and image attached

Explanation:

The acid-catalyzed hydration of 1-methylcyclohexene proceeds by an SN1 mechanism. The reaction involves the formation of carbocations.

Two carbocations are formed leading to the major and minor products. The major product is obtained from the tertiary (more stable) carbocation while the minor product is obtained from the secondary (less stable carbocation).

Tertiary alcohols are not oxidized, hence the major product does not undergo oxidation. However, secondary alcohols are oxidized to ketones.

Which particle decomposes to produce beta radiation?

guajiro [1.7K]

The particle that decomposes to produce beta radiation is NEUTRON.

The neutron decays (udd) into a proton (uud), an electron and an anti-neutrino. This process is known as neutron beta decay and here is how it happens.

The neutron that has a charge of zero is made up of up and two down quarks. One of the down quarks is transformed into an up quark. Since the down quark has a -1/3 charge and the up quarks has a positive charge of 2/3, it immediately follows that this process is mediated by a virtual W particle which carries away a negative charge. The new up quark rebounds away from the emitted W-. Then comes the formation of a proton. An electron and antineutrino them emerge from the virtual W-boson. The proton, electron, and antineutrino will finally move away from one another,

Given the solutes NaCl and I2 and the solvents NH3(ℓ) and C7H16 (heptane), which is true?

stiks02 [169]

Answer:

NaCl is more soluble in NH3 and I2 is more soluble in C7H16

Explanation:

Polar substances are likely to dissolve in polar solvents. For example, ionic compounds, which are very polar, are often soluble in the polar solvent water. Nonpolar substances are likely to dissolve in non-polar solvents.For example, ionic compounds are insoluble in hexane.

In the above example NaCl is a polar compound made up of ions $Na^{+} and \text{ }cl^{-}$ so it is soluble in polar compounds like ammonia (NH3),where as I2 is a non-polar solid so it is soluble in non-polar solvents like n-heptane(C7H16).
