click on the picture of the flowers until their colors correspond to the punnett square above. HELP PLZ!
Answer:
You will need to have a red flower in the top left, a pink flower in the top right and bottom left, and a white flower in the bottom right.
Explanation:
This flower appears to express color through codominance, which means that both genes express themselves. "R" is the dominant gene for red, and "r" is the recessive gene for white. When a flower has RR genotype, the phenotype will be a red flower. When a flower has an Rr genotype, the red and white genes will both be expressed and the phenotype will be pink. When a flower has an rr genotype, it lacks the red gene and will therefore be only white.

Which states of matter change shape when moved? Which states of matter change shape when moved?
Answer:
Gas and Liquids
Explanation:
How do the valency and the atomic size of the element vary while going from left to right along a period in The modern periodic table?
Answer:
Atomic size decreases on going along a period from left to right because the electron enters into the same shell, therefore, attraction between nucleus and outermost electron increases and thus atomic size decreases. Valency first increases from 1 to 4 and then decreases from 4 to GO along a period from left to right.

Explanation:
The fundamental importance of oxygen to life on this planet ensures its place in the care of patients with respiratory disorders. Although now well established for hypoxic patients, many questions remain regarding the benefits of oxygen for varying severity and types of chronic lung disease.
How many grams of oxygen are required to burn 13.5 g of acetylene
Answer:
41.54 grams of oxygen are required to burn 13.5 g of acetylene
Explanation:
The balanced reaction is:
2 C₂H₂ + 5 O₂ → 4 CO₂ + 2 H₂O
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
C₂H₂: 2 moles O₂: 5 moles CO₂: 4 moles H₂O: 2 molesBeing the molar mass of the compounds:
C₂H₂: 26 g/moleO₂: 32 g/moleCO₂: 44 g/moleH₂O: 18 g/moleBy reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
C₂H₂: 2 moles* 26 g/mole= 52 gramsO₂: 5 moles* 32 g/mole= 160 gramsCO₂: 4 moles* 44 g/mole= 176 gramsH₂O: 2 moles* 18 g/mole= 36 gramsYou can apply the following rule of three: if by stoichiometry 52 grams of acetylene react with 160 grams of oxygen, 13.5 grams of acetylene react with how much mass of oxygen?
[tex]mass of oxygen=\frac{13.5 grams of acetylene*160 grams of oxygen}{52 grams of acetylene}[/tex]
mass of oxygen= 41.54 grams
41.54 grams of oxygen are required to burn 13.5 g of acetylene

P4O6
balance the equation
To balance a chemical equation, both sides should have equal mass, or in other words both sides should have same number of atoms as to follow the conservation of mass rule.
P + O₂ = P₄O₆
LHS:
Number of Phosphorus atoms = 1 atom
Number of Oxygen atoms = 2 atoms
RHS:
Number of Phosphorous atoms = 4 atoms
Number of Oxygen atoms = 6 atoms
Also since P₄O₆ has the most number of atoms we will make the LHS equalize to P₄O₆.
Difference between Phosphorous atoms in LHS to RHS = 3
Since phosphorous is a monatomic we need 3 phosphorous atoms extra
Difference between Oxygen atoms is LHS to RHS = 4
But Oxygen is diatomic, so we need 4/2 = 2 Oxygen molecules
Now lets see if it is balanced
P + 3P + O₂ + 2O₂ -------> P₄O₆
4P + 3O₂ ------> P₄O₆
LHS:
Phosphorous atoms = 4 atoms
Oxygen atoms = 3 × 2 = 6 atoms
RHS:
Phosphorous atoms = 4 atoms
Oxygen atoms = 6 atoms
LHS = RHS
Therefore the balanced equation is 4P + 3O₂ = P₄O₆

if 13 moles of Fe react, what is the mass of FeS produced?
Answer:
1144 g of FeS
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
Fe + S —> FeS
From the balanced equation above,
1 mole of Fe reacted to produce 1 mole of FeS.
Therefore, 13 moles of Fe will also react to produce 13 moles of FeS.
Finally, we shall determine mass of 13 moles of FeS. This can be obtained as follow:
Mole of FeS = 13 moles
Molar mass of FeS = 56 + 32
= 88 g/mol
Mass of FeS =?
Mass = mole × molar mass
Mass of FeS = 13 × 88
Mass of FeS = 1144 g
Therefore, 1144 g of FeS were obtained from the reaction.
What is the percent composition of Mg in the compound Mg3(PO4)2?
Question 8 options:
A. 23.57%
B. 21.92%
C. 27.74%
D. 32.32%
Answer:
c
Explanation:
trust me its reasonanle
Per cent composition of Magnesium (Mg) in Magnesium Phosphate compound ie [tex]Mg_3(PO_4)_2[/tex] is 27.74%. Hence, option C is correct.
What is per cent?Percent is from the Latin adverbial phrase per centum meaning “by the hundred.”
Determination of the percentage composition of Mg in Mg₃(PO₄)₂
Molar mass of Mg₃(PO₄)₂ = 262 g/mol
Mass of Mg in Mg₃(PO₄)₂ = 24×3 = 72 g
Percentage composition of Mg =?
[tex]Percentage = \frac{Mass \;of \;elements x 100}{Mass \;of \;compound}[/tex]
[tex]Percentage = \frac{72 X 100}{262}[/tex]
27.74%.
Hence, option C is correct.

3. Describe the process behind how students recover an individual's remains from a surface grave.
Answer:
By using the techniques of archeology.
Explanation:
Students recover an individual's remains from a surface grave by using the techniques of archeology field to scrape away the layers of soil from that remains in a way that the remains can't be damaged. If they find the remains within 10 centimeters of digging, they can dig down further in order to dig out all the remains safely. The instruments of archeology field are used because they are light and can be used to dig out fossils of ancient organisms.

What is a fault, and how does the existence of faults support the theory of plate tectonics?
“Many of the objections are long standing but apparently unknown to many geophysicists, while some are peculiar to the new global tectonics. The conclusions drawn, in order of probability, are (1) the continents have almost certainly not moved with respect to each other; (2) convection is not active throughout the whole mantle; (3) even if convection is active in the upper mantle it cannot account for drift; (4) pole positions derived from paleomagnetism, and results of this method of investigation in its global form generally, are afflicted with an unknown cause of error and are in any case too inexact for drift reconstructions.”
