Answer: Recessive

Explanation: The recessive trait is often faded away by the dominant/other

Also looking at the word dominant it means powerful, most important, influential meaning it would most likely overpower

Goodluck :)

How many moles are there in 987 grams of Ra(OH)2? id also love to know the simplest equation for converting moles --> so i co

OlgaM077 [116]

Mole = $\frac{mass}{molar mass}$

Mass of Radium Hydroxide = 987g
Molar Mass of $Ra(OH) _{2}$ = ((226) + (2 * 16) + (2 * 1))
= 260 g / mol

∴ Moles of <span> $Ra(OH) _{2}$ = </span> $\frac{987 g }{ 260 g / mol }$
= 3.796 mols

if a solution measured with the miscalibrated meter (above) gave a reading of 6.50 at 20oC, what should be the true pH (give 2 d

Andreas93 [3]

Answer:

Explanation:

Ph is the major of acidity or basicity of a solution. On a scale of 0 to 14

PH = -log 10 ^(H+)

Therefore PH= -log 10^(6.5) =0.81

Therefore PH of the solution is 0.81

This solution is therefore an acidic solution

A piece of wood has a labeled length value of 63.2 cm. You measure its length three times and record the following data: 63.1 cm

Ulleksa [173]

Percent error (%)= $\frac{\left | Accepted value - Measured value \right |}{Accepted value}\times 100$

Accepted value is true value.

Measured values is calculated value.

In the question given Accepted value (true value) = 63.2 cm

Given Measured(calculated values) = 63.1 cm , 63.0 cm , 63.7 cm

1) Percent error (%) for first measurement.

Accepted value (true value) = 63.2 cm, Measured(calculated values) = 63.1 cm

Percent error (%)= $\frac{\left | Accepted value - Measured value \right |}{Accepted value}\times 100$

$Percent error = \frac{\left | 63.2 - 63.1 \right |}{63.2}\times 100$

$Percent error = \frac{0.1}{63.2}\times 100$

$Percent error = 0.00158\times 100$

Percent error = 0.158 %

2) Percent error (%) for second measurement.

Accepted value (true value) = 63.2 cm, Measured(calculated values) = 63.0 cm

Percent error (%)= $\frac{\left | Accepted value - Measured value \right |}{Accepted value}\times 100$

$Percent error = \frac{\left | 63.2 - 63.0 \right |}{63.2}\times 100$

$Percent error = \frac{0.2}{63.2}\times 100$

$Percent error = 0.00316\times 100$

Percent error = 0.316 %

3) Percent error (%) for third measurement.

Accepted value (true value) = 63.2 cm, Measured(calculated values) = 63.7 cm

Percent error (%)= $\frac{\left | Accepted value - Measured value \right |}{Accepted value}\times 100$

$Percent error = \frac{\left | 63.2 - 63.7 \right |}{63.2}\times 100$

$Percent error = \frac{\left | -0.5 \right |}{63.2}\times 100$

$Percent error = \frac{(0.5)}{63.2}\times 100$

$Percent error = 0.00791\times 100$

Percent error = 0.791 %

Percent error for each measurement is :

63.1 cm = 0.158%

63.0 cm = 0.316%

63.7 cm = 0.791%
