Hi,
I don't think it can affect humans because humans and birds don't get into contact with each other. An insect and a human do, therefore a human could be affected, but a bird doesnt.

How much heat, in kJ, is released when 6 mol of water at 0°C freezes to ice at 0°C if ΔHsolid for water = –6.01 kJ/mol?
Answer:
12.3 kJ
Explanation:
For a given substance, the molar heat of fusion basically tells you one thing from two perspectives
how much heat is needed in order to melt one mole of that substance at its melting point
how much heat must be removed in order to freeze one mole of that substance at its freezing point
It is very important to realize that the molar enthalpy of fusion will carry a positive sign when you're dealing with melting and a negative sign when you're dealing with freezing.
The molar mass of element X is 42.3 grams per mol and the molar mass for
element Y is Y 96.7 grams per mol. What is the empirical formula for a substance
containing a mass composition of 52.2% X and the remainder Y?
Answer:
X5Y2
Explanation:
% composition of X = 52.2%
% composition of Y = (100 - 52.2) = 47.8%
This means that there are 52.2g of X and 47.8g of Y in the compound
To calculate the empirical formula of the compound, we first convert the gram value to mole value by dividing by their molar masses.
X = 52.2g/42.3g/mol = 1.234mol
Y = 47.8g/96.7g/mol = 0.494mol
Next, we divide each mole value by the smallest value (0.494mol)
X = 1.234mol ÷ 0.494mol = 2.49
Y = 0.494mol ÷ 0.494mol = 1
We multiply each value by 2
X = 2.49 × 2 = 4.98
Y = 1 × 2 = 2
The simple ratio of X:Y is 5:2, hence, their empirical formula is X5Y2.

definition of atomic number
The atomic number or proton number (symbol Z) of a chemical element is the number of protons found in the nucleus of every atom of that element. The atomic number uniquely identifies a chemical element. It is identical to the charge number of the nucleus. In an uncharged atom, the atomic number is also equal to the number of electrons.
Answer:
its basically represents the number of protons in the nucleus which in a neutral atom equals the number of electrons outside the nucleus and that determines the place of the element in the periodic table

When Svante Arrhenius first proposed his acid base theory, he was a doctoral candidate. His professors thought his ideas were unfounded. Within a decade, the Arrhenius theory of acid base was widely accepted and praised within the scientific world. Arrhenius defined acids as compounds having an ionizable hydrogen and bases as compounds with ionizable hydroxides. Eventually scientists adopted a broader theory which includes more compounds to define acids and bases. The Bronsted-Lowry acid base theory defines an acid as a _______ and a base as a ______________.
Answer:
proton donar
proton acceptor
Explanation:
From the given information of the question, Arrhenius acid and base concept is explained, from which a better term to define an acid and base is defined, known as The Bronsted-Lowry acid base theory.
According to The Bronsted-Lowry acid base theory -
An acid is the species which can readily donate a proton, where as, a base is the species, which can readily accept a proton.
Hence, the correct answer is as follow -
proton donar
proton acceptor
Answer:
proton donar
proton acceptor

Consider the table below that summarizes the types of materials that can block the 3 different types of radiation. Based on the table, at which numbered spot in the table does each type of radiation belong. 1 = beta; 2 = alpha, 3 = gamma
Answer:
D. 1 = gamma; 2 = alpha, 3 = beta
Explanation:
I apologize if this answer is late, but I got answered the question right on my "Types of Radioactive Decay" quiz :)
Hope this is helpful for others! :D
Based on the table, the type of radiation belong from 1 is the gamma rays, from 2 is the aplha rays and from 3 is the beta rays.
What are radiations?During the radioactive decay process, some amount of energy is released in the form of particles and that radiations will known as alpha rays, beta rays and gamma rays.
Gamma ray are mare energetic rays and will shielded by only lead and thick concrete materials.Beta rays are less energetic than gamma rays and will shielded by lead, cloth, paper, wood, aluminium foil and thick concrete materials.Aplha rays have very less amount of energy in it and it will be shielded by all above mention materials.Hence 1 is the gamma rays, 2 is the aplha rays and 3 is the beta rays.

Mass=
g give your answer to two significant figures.
Answer:
60g
Explanation:
The molar mass of a substance (Atom or molecule) is defined as the mass in grams that 1 mole of substance (6x10²³ particles of this substance) weighs. Using the periodic table of elements we can know the molar mass of each atom.
For example, the molar mass of Calcium is 40.078g / mol.
That means the mass of 1.5 moles of calcium atoms must be:
1.5 moles * (40.078g / mol) =

Determine the volume of the product containing carbon produced when 15.0 g of C2H2 are reacted with an excess of oxygen gas
Answer:
25.8 L
Explanation:
Step 1: Write the balanced equation for the complete combustion of acetylene
C₂H₂ + 2.5 O₂ ⇒ 2 CO₂ + H₂O
Step 2: Calculate the moles corresponding to 15.0 g of C₂H₂
The molar mass of C₂H₂ is 26.04 g/mol.
15.0 g × 1 mol/26.04 g = 0.576 mol
Step 3: Calculate the moles of CO₂ produced from 0.576 moles of C₂H₂
The molar ratio of C₂H₂ to CO₂ is 1:2. The moles of CO₂ produced are 2/1 × 0.576 mol = 1.15 mol.
Step 4: Calculate the volume corresponding to 1.15 moles of CO₂
At standard temperature and pressure, 1 mole of CO₂ occupies 22.4 L.
1.15 mol × 22.4 L/1 mol = 25.8 L

How many grams of
carbon dioxide will be
produced if 135 grams

reacted?
Answer:
36.5 g CO2
Explanation:
First, Write a Balanced Equation
C + 2 ZnO → CO2 + 2 Zn
Useful Information,
MW of ZnO = 81.41 g
MW of CO2 = 44.01 g
135 g ZnO x (1 mol ZnO / 81.41 g ZnO) x (1 mol CO2/2 mol ZnO) x ( 44.01 g CO2 / 1 mol CO2 ) = 36.5 g CO2
You have a gas that has a pressure of 2 ATM and a volume of 10 L. What would be the new volume if the pressure was changed to 1 ATM ?
Answer:
20 LExplanation:
The new volume can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we're finding the new volume
[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]
We have
[tex]V_2 = \frac{2 \times 10}{1} = 20 \\ [/tex]
We have the final answer as

Which bond would be the least polar?
1) H-Br (hydrogen-bromine)
2) H-F (hydrogen-fluorine)
3) H-H (hydrogen-hydrogen)
4) H-O (hydrogen-oxygen)
Answer:
[tex]\boxed {\boxed {\sf 3. \ H-H}}[/tex]
Explanation:
To determine the polarity of a bond, we use the electronegativities of the individual atoms. The greater the difference, the more polar the bond.
1. H-Br
Hydrogen: 2.2 Bromine: 3.03.0-2.2=0.8
2. H-F
Hydrogen: 2.2 Fluorine: 4.04.0-2.2=1.8
3. H-H
Hydrogen: 2.22.2-2.2=0.0
4. H-O
Hydrogen: 2.2Oxygen: 3.43.4-2.2=1.2
As we can see, the lowest difference is in hydrogen hydrogen at 0.0. You may also recognize that because they are 2 atoms of the same element, the electronegativity is the same for both, so it will equal 0. Since the electronegativity is 0, this is a nonpolar bond.

If 34.2 g of NaOH are dissolved in water to make a 750 mL solution, what is the molarity of the solution?
Answer:
1.14 M
Explanation:
First divide the mass of NaOH by the molar mass of NaOH. Then divide by the volume to get molarity.
34.2 g / 39.997 g/mol = 0.855 mol NaOH
0.855 mol NaOH / 0.750 L = 1.14 M NaOH
