Answer:

Zn(NO₃)₂

Explanation:

this single replacement reaction will produce silver metal, Ag , and aqueous zinc nitrate, Zn(NO3)2 . Zinc is above silver is the metal reactivity series, so it will replace silver in silver nitrate

Answer:

9.3 x 10^ -5 in standard notation is 0.000093

Explanation:

Since 10 is raised to a -5, this means that there should be 5 zeros before the non-zero digits

A hot metal is placed in 100.0 g sample of water and it causes the temperature of the water to increase from 25 C to 27 C. How m

Arisa [49]

Answer: $836.8\ J$

Explanation:

Given

Mass of water in the sample is $m=100\ g$

Temperature changes from $25^{\circ}C$ to $27^{\circ}C$

Change in temperature is $\Delta T=27-25=2^{\circ}C\ \text{or}\ 2\ K$

We know, specific heat of water is $c=4.184\ J/g-K$

Heat absorbed is given by

$\Rightarrow Q=mc\Delta T\\\Rightarrow Q=100\times 4.184\times 2\\\Rightarrow Q=836.8\ J$

Thus, water absorbs $836.8\ J$ of heat from hot plate.

Fluorine has an atomic number 9. It is in period 2 of the periodic table. The diagram shows the electron dot diagram of a fluori

jek_recluse [69]

Fluorine has C seven valence electrons.

Valence electrons are the electrons that are found on the outer shell of an atom that are capable of participating in chemical reactions. The easiest way to figure out how many valance electrons Fluorine has would be to look it up in a periodic table and notice that it a group 7 element and therefore has 7 valence electrons.

The other way to tell that Fluorine has 7 valence electrons is to notice that an element with an atomic number of 9 has 9 electrons. The electronic configuration of elements has the first 2 electrons go on the first shell or energy level $1s^2$ , the leaving the next 7 to go to the second shell $2s^22p^5$ which can take up to 8 electrons.
