C. The electric potential (volts) divided by the current (amperes) equals the resistance (ohms)

The correct answer is option C, that is, the electric potential (volts) divided by the current (amperes) equals the resistance (ohms).  

According to the Ohm's law, the current via a conductor between the two points is directly equivalent to the voltage through the two points. With the introduction of resistance, that is, the constant of proportionality, the mathematical equation, which describes the association is:  

I = V/R

Here, I is the current via the conductor in the units of amperes, R is the resistance of the conductor in the units of ohms, and V is the voltage determined across the conductor in the units of volts.

11111nata11111 [884]

ANSWER

\begin{gathered} \text{ 2KBr }+\text{ CaO }\rightarrow\text{ K}_2O\text{ }+\text{ CaBr}_2 \\ Option\text{ B} \end{gathered}

EXPLANATION

Given that;

The two reactants are KBr and CaO

Double replacement reaction is a type of chemical reaction that occur when two reactants exchange cations and anions to yield new products.

\text{ 2KBr + CaO  }\rightarrow\text{ K}_2O\text{ + CaBr}_2

Therefore, the resulting products of the given data are K2O + CaBr2

The correct answer is option B

HELP PLS !!!! :))Formula unit of Sr and CI<br><br> Formula unit of AI and S
xenn [34]

Answer : The formula unit of Sr & Cl is SrCl_2 and the formula unit of Al & S is Al_2S_3

Explanation :

Formula unit : it is defined as the lowest number ratio of ions of an elements in an ionic compound or covalent compound.

For the formula unit of Sr & Cl, two chloride ions(Cl^-) are needed to neutralize the one strontium ion(Sr^{2+}).

For the formula unit of Al & S, three sulfide ions(S^{2-}) are needed to neutralize the two aluminium ion(Al^{3+}).

The formula unit of SrCl_2 and Al_2S_3 are shown below.

Solution (A) contains 0.01 M of NH4Cl; solution
ArbitrLikvidat [17]

Answer:

NH4Cl, NaCl, Ba(OH)2, NaOH

Explanation:

NH4Cl is an acidic salt formed by the neutralization of a strong acid (HCl) with a weak base (NH3). Hence, it will habe a PH<7 (the lowest PH).

NaCl is a neutral salt,formed by neutralization of a strong acid (HCl) with a strong base (NaOH). Hence, it will have a PH of 7.

Ba(OH)2 is a weak base. Therefore, it will have a PH between 8 and 10.

NaOh meanwhile, is a strong base. Therefore, it will have a PH between 10 to 13.

Hence, we have

NH4Cl < NaCl < Ba(OH)2 < NaOH
