Answer:

Schistosoma or blood fluke

Explanation:

Parasitic organisms are defined as the organisms that depends on other organisms body called host for their nutrition and harm the host body.

The given image is of Schistosoma that is commonly known as blood flukes. Schistosoma are flatworms which causes group of infections in humans known as schistosomiasis. Schistosoma is a water-borne parasite and found in veins near the human intestine.

Hence, the correct answer is "Schistosoma or blood fluke".

The combustion of palmitic acid is represented by the chemical equation: C16H32O2(s) + 23O2(g) → 16 CO2(g) + 16 H2O(l) The magni

solniwko [45]

Answer:

The correct option is C

Explanation:

From the question we are told that

The reaction is

$C_{16}H_{32}O_2(g) + 23O_2(g) \to 16 CO_2(g) + 16 H_2O(l)$

Generally $\Delta H = \Delta U + \Delta N* RT$

Here $\Delta H$ is the change in enthalpy

$\Delta U$ is the change in the internal energy

$\Delta N$ is the difference between that number of moles of product and the number of moles of reactant

Looking at the reaction we can discover that the elements that was consumed and the element that was formed is $O_2$ and $CO_2$ and this are both gases so the change would occur in the number of moles

$\Delta H = \Delta U + [16 -23]* RT$

$\Delta H = \Delta U -7RT$

The negative sign in the equation tell us that the enthalpy $\Delta_r H$ would be less than the Internal energy $\Delta_r U$

1. How many atoms are there in 2.8 moles of carbon? You must show your work to receive credit.

Zolol [24]

Answer:

The answer to your question is

1.- 1.686 x 10²⁴ atoms

2.- 0.25 moles

Explanation:

1.-

1 mol ---------------- 6.023 x 10²³ atoms

2.8 moles ---------- x

x = (2.8 x 6.023 x 10²³) / 1

x = 1.686 x 10²⁴ atoms

2.- 1 mol ------------------ 6.023 x 10 ²³ molecules

x moles ------------- 1.50 x 10²³ molecules

x = (1.50 x 10²³ x 1) / 6.023 x 10²³

x = 0.25 moles

The theoretical yield of Cl2 from certain starting amounts of MnO2 and HCl was calculated as 60.25 g and 65.02 g, respectively.

user100 [1]

Answer:

c 43.38 g

Explanation:

The reaction between MnO2 and HCl can be represented by the following balanced equation:

MnO2 + HCl ---> Cl2 + MnCl2 + H2O

From the balanced equation, the theoretically required molar ratio of MnO2 to HCl is 1:1, therefore the yields would have been expected to be equal.

For the fact that HCl gives a higher yield (65.02g) than MnO2 (60.25g) according to the problem statement, HCl should be in excess, while the limiting reagent should be MnO2 .

Thus, the theoretical yield of Cl2 will be 60.25 g.

By definition, the percentage yield is given by

% Yield = (Actual Yield) / (Theoretical Yield),

This can be simplified to

Actual Yield = % Yield * Theoretical Yield

Plugging in the given values we have

Actual Yield = 72% * 60.25 = 43.38 g
