Which pair of elements can form ionic bonds?
A.
copper (Cu) and nitrogen (N)
B.
gallium (Ga) and phosphorus (P)
C.
hydrogen (H) and sulfur (S)
D.
phosphorus (P) and fluorine (F)
E.
potassium (K) and bromine (Br)
Answer:
E. potassium (K) and bromine (Br)
Explanation:
An ionic bond is formed between compounds with a large electronegativity difference between them. It is usually between a metal and non-metal.
Potassium is a true metal found in group 1 on the periodic table. Bromine is a highly electronegative non-metal which is a halogen. Potassium will lose one of its electrons which will be gained by the Bromine. The electrostatic attraction between the two species will cause the ionic bond to form. The ability of one specie willing to lose electron and the other gaining, is the main bed rock of ionic bonding.Answer:
Correct answer: E. potassium (K) and bromine (Br)

Consider the reaction: 3 N2 (g) + 2 O3 (g) → 6 NO (g) ΔfH ° (kJ/mol) 0.00 142.26 90.37 Sm ° (J mol-1 K-1) 191.5 237.7 210.6 What is ΔrG ° for this reaction in kJ/mol at 350 K?
Answer:
Explanation:
3 N₂ (g) + 2 O₃ (g) → 6 NO (g)
Δ H(rxn ) = 90.37x 6 - ( 0 + 142.26 x 2 )
= 542.22 - 284.52
= 257.7 kJ
Δ S(rxn ) = 6 x 210.6 - ( 2 x 237.7 + 3 x 191.5 )
= 1263.6 - ( 475.4 + 574.5 )
= 213.7 J / K
Δ G = Δ H - T Δ S
= 257.7 - 350 x 213.7
= - 74537.3 kJ .
Δ G / mole = - 74537.3 / 6 = - 12422.88 kJ / mol.

How much heat is required to raise the temperature of a 6.21 g sample of iron from 25.0 oC to 79.8 oC?
Answer:
151.1J
Explanation:
Given parameters:
Mass of iron = 6.21g
Initial temperature of iron = 25°C
Final temperature of iron = 79.8°C
Unknown:
Amount of heat = ?
Solution:
The amount of heat require to cause this temperature can be determined using the expression below;
H = m c (T₂ - T₁)
H is the amount of heat
m is the mass
c is the specific heat capacity
T is the temperature
Specific heat capacity of iron 0.444J/g°C
Insert the parameters and solve;
H = 6.21 x 0.444 x (79.8 - 25)
H = 151.1J

(1) Antimony
(2) Sodium
(3) Aluminium
(4) Helium
Antimony
Hope it helps
Answer:
[tex]\boxed {\boxed {\sf 1. \ Antimony}}[/tex]
Explanation:
A metalloid is an element that is "in between" a metal and non-metal. They display some properties of both.
On the Periodic Table, the metalloids are found in a zig-zag step pattern to the right of the metals and the left of the non-metals.
There are 7 metalloids: boron, silicon, germanium, arsenic, antimony, tellurium, and polonium.
So, the correct answer is 1. Antimony

Answer:
D Protons/negative; neutrons/neutral; electrons/negative
Explanation:
There are three fundamental subatomic particles found in atom which are the protons, neutrons and electrons.
Protons are the positively charged particlesNeutrons are neutral and do not carry any chargesElectrons are negatively charged.In the tiny central nucleus, both protons and neutrons can be found
The electrons occupy the bulk volume of the atom.

When an element in the first group of the periodic table
reacts with an element in the seventh group, what is the
type q bond that is likely to be formed?
Answer:
An ionic bond
Explanation:
They are most likely going to form an ionic bond.
An ionic bond is where atoms lose/gain electrons.
It is easier for elements in the first group to lose the one electron on their valence shell and for elements in the second group to take that.
Some examples are Sodium Chloride (NaCl) and Potassium Chloride (KCl)

Answer:
Transparent Rock Crystal has many electronic uses; it is used as oscillators in radios, watches, and pressure gauges, and in the study of optics. Quartz is also used as an abrasive for sandblasting, grinding glass, and cutting soft stones.
Explanation:
A very hot cube of copper metal (32.5 g) is submerged into 105.3 g of water at 15.4 0C and it reach a thermal equilibrium of 17.3 0 Calculate the initial temperature of copper (Cs = 0.385 J/g 0C for copper, and 4.18 J/g 0C for water).
Answer:
The initial temperature of the metal is 84.149 °C.
Explanation:
The heat lost by the metal will be equivalent to the heat gain by the water.
- (msΔT)metal = (msΔT)water
-32.5 grams × 0.365 J/g°C × ΔT = 105.3 grams × 4.18 J/g °C × (17.3 -15.4)°C
-ΔT = 836.29/12.51 °C
-ΔT = 66.89 °C
-(T final - T initial) = 66.89 °C
T initial = 66.89 °C + T final
T initial = 66.89 °C + 17.3 °C
T initial = 84.149 °C.
What would happen if a researcher failed to realize a thermometer he or she was using has a Celsius and Fahrenheit scale?
Answer:
To obtain a more accurate read on temperature, the researcher should make sure to measure temperature by Celsius degrees rather than Fahrenheit.
Explanation:
Temperature is a measure of heat intensity. In food science experiments, you should always require an exact description of heat intensity. The most commonly used unit of temperature in the laboratory is the Celsius degree because the Celsius temperature scale is based on the boiling and freezing points of pure water. The difference between the points of boiling and freezing temperatures (at 1 atmosphere of air pressure) is divided into 100 equal units, making a Celsius degree 0.01 of the difference between the boiling and freezing points of water, making it the most accurate method of exact temperature reading. It is important to use the Celsius scale if you have a thermometer that reads Celsius and Fahrenheit.
