Conductors have(blank) resistance. Moderate. Very High. Very low.

Flura [38]

Answer:

The correct option is C) Very low

Explanation:

In physics, resistance can be described as the opposition to the flow of current or the flow of electrons. Conductors are known to be materials which can conduct electricity. Hence, conductivity and resistance are opposite to each other. Good conductors will have very little or no resistance and will have enhanced conductivity. On the contrary, insulators are materials which will have more resistance and they cannot conduct electricity as efficiently.

The reaction of HCl with NaOH is represented by the equation HCl( aq) + NaOH( aq) ® NaCl( aq) + H 2O( l) What volume of 0.631 M

Darina [25.2K]

8.04 mL.

<h3>Explanation</h3>

How many moles of NaOH?

Note the unit:

$V = 15.8 \; \textbf{mL} = \dfrac{15.8}{1000}\;\textbf{L} = 0.0158 \; \text{L}$ .

$n = c\cdot V = 0.0158 \times0.321 = 0.00507\;\text{mol}$ .

How many moles of HCl?

As seen in the equation, HCl and NaOH reacts at a 1:1 ratio.

$n(\text{HCl}) = n(\text{NaOH}) = 0.00507\;\text{mol}$ .

How many mL of HCl?

$V = \dfrac{n}{c} =\dfrac{0.00507}{0.631} = 0.00804\;\text{L} = 0.00804\times 1000 \;\textbf{mL} = 8.04\;\text{mL}$ .

Write the balanced nuclear equation for the following. (Use the lowest possible coefficients. Omit states-of-matter in your answ

olga55 [171]

Answer:

$_{93}^{232}\text{Np} + _{-1}^{0}\text{e} \longrightarrow _{92}^{232}\text{U}$

Explanation:

The unbalanced nuclear equation is

$_{93}^{232}\text{Np} + _{1}^{0}\text{e} \longrightarrow ?$

It is convenient to replace the question by an atomic symbol, $_{x}^{y}\text{Z}$ , where x = the atomic number, y = the mass number, and Z = the symbol of the element.

$_{93}^{232}\text{Np} + _{1}^{0}\text{e} \longrightarrow _{x}^{y}\text{Z}$

Then your equation becomes

$_{93}^{232}\text{Np} + _{1}^{0}\text{e} \longrightarrow _{x}^{y}\text{Z}$

The main point to remember in balancing nuclear equations is that the sums of the superscripts and of the subscripts must be the same on each side of the equation.

Then

93 – 1 = x, so x = 92

232 + 0 = y, so y = 232

Element 92 is uranium, so the nuclear equation becomes

$_{93}^{232}\text{Np} + _{-1}^{0}\text{e} \longrightarrow _{92}^{232}\text{U}$
